Description

The proposed method and device relates to the field of search and rescue operations and can be used to search for bombarded bioobjects or their remains in earthquake areas, as well as in mountaineering when searching for bioobjects bombarded with, for example, avalanches or mountain landslides.

Known methods and devices for detecting the location of buried biological objects or their remains (RF patents Nos. 2,085.997, 2.105.432, 2.116.099, 2.206.902, 2.248.235, 2.288.486, 2.370.792; US patents Nos. 4.129. 868, 4.331.957, 6.031.482; EP patents No. 0.075.199, 1.746.433; Vinokurov V.K. et al. Safety in mountain climbing. - M., 183, S.136-137; V. Dikarev Safety, protection and salvation of a person. - SPb, 2007, S.460-467, and others).

Of the known methods and devices closest to the proposed one is the "Method for locating buried biological objects or their remains and a device for its implementation" (RF patent No. 2,370.792, G01V 3/12, 2007), which are selected as the base objects.

The known method and device provide an extension of functionality by determining the distance to a source of radio emission (IRI) (a buried biological object or its remains). In this case, the correlation processing and the correlation function R (τ) are used (Fig. 8, a).

However, in the region of the maximum, the correlation function R (τ) has a small slope and changes insignificantly with changes in τ, which reduces the accuracy of determining the distance to the IRI. Much more favorable for finding the maximum is the form of the derivative of the correlation function dR (τ) / dτ (Fig. 8, b). At the point τ = 0, the derivative has a significant steepness and, in addition, changes sign depending on the position relative to the point τ = 0.

Thus, finding the maximum of the correlation function (the maximum principle is an extreme problem) is replaced by the minimum principle - stabilization of the zero value of the controlled variable.

In addition, to determine the direction to the source of radio emissions (bioobject or its remains), an antenna with a wide radiation pattern is used, which does not have a pronounced extremum point, which also reduces the accuracy of determining the azimuth (bearing) for IRI. To form a narrow radiation pattern, a complex antenna system of large dimensions is required, which is not always technically feasible in practice. It is advisable to use a vibrating and loop antenna, which form a circular and cardioid radiation patterns, i.e. the minimum method is used.

Consequently, the low accuracy of determining the range and azimuth of a source of radio emissions leads to low accuracy in determining the location of buried biological objects or their remains.

An object of the invention is to increase the accuracy of determining the location of buried biological objects or their remains by using the derivative of the correlation function, vibrator and frame antennas.

The problem is solved in that a method for detecting the location of buried bioobjects or their remains, based on the closest analogue on that previously placed on a bioobject belonging to the risk group, is a low-power transceiver, which is used as a piezocrystal with an aluminum counter-coated on its surface a pin transducer associated with a microstrip antenna and a set of reflectors form a high-frequency oscillation with a carrier frequency ω _c , transform it by the frequency frequency using the frequency ω _g local oscillator, isolate the voltage of the first intermediate frequency ω _pr1 equal to the sum of the frequency ω _pr1 = ω _g + ω _s , amplify it in power, irradiate with the help of a scanning unit a covered area, under the surface of which there may be a biological object or its remains directed by an electromagnetic signal, receive it on a bombarded biological object or its remains, convert it into an acoustic wave, ensure its propagation on the surface of the piezocrystal and back reflection, convert the reflected acoustics wave again into an electromagnetic signal with phase shift keying, the internal structure of which corresponds to the structure of the interdigital transducer, the generated signal with phase shift keying is re-emitted by the microstrip antenna into the ether, receive by its scanning unit antenna, amplified by the amplitude, the received signal with phase shift keying at the first intermediate frequency ω _CR1 , repeatedly converted in frequency using the carrier frequency ω _c , the voltage of the second intermediate frequency ω _CR2 = ω _{CR1 -ω c} = ω _g , reg the selected modulating code corresponding to the structure of the interdigital transducer is abutted, analyzed and the affiliated bioobject or its remains are identified, the local oscillator voltage is delayed for a time τ, differs from the closest analogue in that the antenna system of the scanning unit is made in the form of vibrating and loop antennas, which fixed on the platform with the possibility of its rotation in the horizontal plane, summarize the complex signals with phase shift keying received vibrator and loop antenna By forming a cardioid radiation pattern, the total signal is amplified in amplitude, it is detected and the detected signal received by the vibrator antenna is divided by the detected total signal, the obtained voltage is compared with the threshold voltage and if it is exceeded, which corresponds to the coincidence of the zero dip of the cardioid radiation pattern with a direction to the source of radio emissions, allow further processing of the received signals, during which nhronnoe detection of the received signal with phase shift keying on the second intermediate frequency ω _np2 = ω _T, the voltage of the second intermediate frequency is differentiated with respect to time and multiplied with the voltage oscillator delayed by time τ, emit a low-frequency voltage proportional to the derivative of the correlation function dR (τ) / dτ, reinforce it, change the delay time τ until equality τ = 0, maintain the indicated equality, which corresponds to the zero value of the derivative of the correlation function dR (τ) / dτ, determine the distance the brightness of R to the bombarded biological object or its remains, the signal received by the vibrating antenna with the total signal is compared in phase, the control voltage is formed, the amplitude and polarity of which correspond to the degree and side of the deviation of the zero dip of the cardioid radiation pattern from the direction to the source of radio emissions, they affect the executive bodies platforms, eliminating the inconsistency.

The problem is solved in that a device for detecting the location of buried bioobjects or their remains, containing, in accordance with the closest analogue, a transceiver located on a bioobject belonging to a risk group and made in the form of a piezoelectric crystal with an aluminum thin-film interdigital transducer deposited on its surface, associated with a microstrip antenna, and a set of reflectors, while the interdigital transducer contains two comb systems of electrodes, electrodes each one of the combs is connected to each other by buses connected to a microstrip antenna, and a scanning unit consisting of a serially connected master oscillator, a first mixer, the second input of which is connected by the first output of the local oscillator, the amplifier of the first intermediate frequency, the power amplifier, the circulator, the input-output of which connected to the transceiver antenna, the first high-frequency amplifier, the second mixer, the second input of which is connected to the output of the master oscillator, and the amplifier of the second intermediate frequency, subsequently properly connected to the second output of the local oscillator of the adjustable delay unit, multiplier and low-pass filter, connected in series to the second output of the adjustable delay unit of the first phase detector and computer, the second input of which is connected to the output of the adjustable delay unit, a range indicator is connected to the second output of the adjustable delay unit, differs from the closest analogue in that the scanning unit is equipped with a platform, an angle indicator, a gearbox, an adder, a second high-frequency amplifier, two amplitude detectors, a division block, a threshold block, an amplifier, two keys, a second phase detector, a motor and a control voltage generating unit, the transceiver antenna being made in the form of an antenna system consisting of a vibrating and loop antennas located on the platform and connected through the adder to the series connected to a second high-frequency amplifier, a second amplitude detector, a division unit, the second input of which is connected to the output of the first amplifier through the first amplitude detector For high frequency, the threshold block, the first key, the second input of which is connected to the output of the intermediate frequency amplifier, and the differentiator, the output of which is connected to the second input of the multiplier, the output of the low-pass filter through the amplifier is connected to the second input of the adjustable delay unit, the input of the first phase detector is connected with the output of the first key, the second phase detector is connected in series to the output of the first high-frequency amplifier, the second input of which is connected to the output of the second high-frequency amplifier, the unit Bani control voltage and a motor connected through a gearbox to the platform, provided with a reducer angle pointer.

The radiation pattern, direction-finding characteristics and the appearance of the receiving antennas are shown in Figs. 5, 6 and 7. The correlation function R (τ) and its derivative dR (τ) / dτ are shown in Fig. 8.

A device that implements the proposed method contains a scanning unit and a transceiver.

The scanning unit contains a serially connected master oscillator 1, a first mixer 9, the second input of which is connected to the first output of the local oscillator 8, an amplifier 10 of the first intermediate frequency, a power amplifier 2, a circulator 3, the input-output of which is connected to a transceiver antenna 4, a high-frequency amplifier 5 , a second mixer 11, the second input of which is connected to the output of the master oscillator 1, an amplifier 12 of the second intermediate frequency, the first key 34, a phase detector 6, the second input of which is connected to the adjustable delay unit 23 with about the second output of the local oscillator 8, a multiplier 20, the second input of which through a differentiator is connected to the output of the first key 34, a low-pass filter 21, an amplifier 22, an adjustable delay unit 23 and a range indicator 24. The multiplier 20, the low-pass filter 21, the amplifier 22 and the adjustable delay unit 23 form a correlator 19.

The transceiver antenna 4 is made in the form of an antenna system consisting of a vibrator 4.1 and a frame 4.2 antennas located on the platform 26 and connected via an adder 28 to a second high-frequency amplifier 29, a second amplitude detector 31, a division unit 32, the second input of which through the first an amplitude detector 30 is connected to the output of the first high-frequency amplifier, a threshold unit 33, a second key 35, the second input of which is connected to the output of the first high-frequency amplifier 5, the second phase detector 37, the second od coupled to an output of the second amplifier 29, high frequency unit 39 generating the control voltage and the motor 40 coupled through a reduction gear 25 to the platform 26. The gearbox 25 is provided with an angle indicator 27. The second input of the first key 34 is connected to the output of the threshold unit 33. The control voltage generating unit 39 and the motor 40 form the antenna system radiation pattern control unit 38.

The transceiver unit is made in the form of a piezocrystal 13 with an aluminum thin-film interdigital transducer deposited on its surface connected to a microstrip antenna 14 and a set of reflectors 18.

The interdigital transducer of surface acoustic waves (SAW) contains two comb systems of electrodes 15, buses 16 and 17, which will connect the electrodes of each of the combs to each other. Tires 16 and 17, in turn, are connected to the microstrip antenna 14.

The proposed method is implemented as follows. The master oscillator 1 is formed of high-frequency oscillation (figure 4, a)

u _c (t) = U _c cos (ω _c t + φ _c ), 0≤t≤T _c ,

where U _c , ω _c , φ _s , T _c - amplitude, carrier frequency, initial phase and duration of high-frequency oscillations,

which is fed to the first input of the first mixer 9, the second input of which is the voltage of the local oscillator 8 (Fig.4, b)

u _Г (t) = U _Г cos (ω _Г t + φ _Г ).

The output of the mixer 9 is formed voltage of the Raman frequencies. The amplifier 10 is allocated the voltage of the first intermediate (total) frequency (figure 4, c)

u _CR1 (t) = U _CR1 cos (ω _CR1 t + φ _CR1 ), 0≤t≤T _c

;Where $$U_{PR\mathrm{one}}=\frac{\mathrm{one}}{2}{K}_{\mathrm{one}}{U}_c{U}_G$$

;

K ₁ - gear ratio of the mixer;

ω _CR1 = ω _s + ω _G - the first intermediate (total) frequency;

φ _pr1 = φ _s + φ _G ,

which, after amplification in the power amplifier 2, through the circulator 3 enters the horn transceiver antenna 4 and is broadcast. With the help of a horn antenna 4, a bombarded area is sequentially irradiated, where the biological object or its remains are supposedly located.

The electromagnetic signal u _pr1 (t) is received by the microstrip antenna 14 of the transceiver located on the biological object or its remains. The latter is a piezocrystal 13 with an aluminum thin-film interdigital SAW transducer deposited on its surface, which consists of two comb systems of electrodes 15 deposited on the surface of the piezocrystal 13. The electrodes of each of the combs are connected to each other by buses 16 and 17. Tires turn connected to microwave antenna 14.

The principle of operation of the interdigital transducer of a surfactant is based on the fact that the electric fields in space and time created in a piezoelectric crystal by a system of electrodes cause elastic strains due to the piezoelectric effect, which propagate in the crystal as a surfactant. Surface acoustic waves are waves propagating along the surface of solids in a relatively thin surface layer. The propagation velocity of surfactants in crystals is approximately five orders of magnitude lower than the propagation velocity of electromagnetic waves. This means that on the centimeter of the crystal, you can place information that will fill a kilometer-long cable.

The high information capacity of instruments based on surface acoustic waves was first used in delay lines, which make it possible to store, transform, channel, divert and reflect the signals propagating in them.

The basis of the operation of devices on surfactants are three physical processes:

- conversion of the input electrical signal into an acoustic wave;

- propagation of an acoustic wave along the surface of the sound duct;

- the inverse transformation of the surfactant into an electrical signal. For direct and inverse conversion of surfactants, transducers of surface acoustic waves are used. The most common among which received interdigital converters.

The _received harmonic oscillation u _pr1 (t) is converted by an interdigital transducer into an acoustic wave that propagates along the surface of the piezoelectric crystal 13, is reflected from a set of 18 reflectors and is again converted into an electromagnetic signal with phase shift keying (QPS) (Fig. 4, e)

u ₂ (t) = U ₂ cos [ω _{CR 1} t + φ _k (t) + φ _{CR 1} ], 0≤t≤E _s ,

where φ _к = {0, π} is the manipulated phase component that displays the phase manipulation law in accordance with the modulating code M (t) (Fig. 4), and φ _к (t) = const for kτ _Э <t <(k +1) τ _E and can change stepwise at t = kτ _e , i.e. at the borders between elementary premises (k = 1, 2, ..., N-1);

τ _E , N - the duration and number of chips that make up a signal of duration T _c (T _c = Nτ _E ).

In this case, the internal structure of the generated PSK signal is determined by the topology of the interdigital transducer, has an individual character and contains all the necessary unique information about the owner, for example, last name, first name, middle name, year of birth, etc.

The generated FM signal u ₂ (t) is radiated by the microstrip antenna 14, received by the vibrating 4.1 and 4.2 antenna antennas of the antenna system 4 of the scanning unit and through the circulator 3, adder 28, amplifiers 5, 29 and amplitude detectors 30, 31 are fed to two inputs block 32 divisions.

The amplitude of the signal at the output of the amplitude detector 30 does not depend on the direction of arrival of the input signal due to the circular radiation pattern of the vibrator antenna 4.1 (figure 5).

The loop antenna 4.2 together with the vibrator antenna 4.1 form a cardioid radiation pattern. The loop antenna 4.2 together with the vibrator antenna 4.1 form a cardioid radiation pattern that rotates until the zero dip coincides with the direction of arrival of the signal (Fig. 5). The amplitude of the signal from this direction at the output of the amplitude detector 31 is close to zero, therefore, at the moment the output of the division unit 32 will have a maximum voltage, which from the output of the division unit 32 is compared with the threshold voltage U _then in the threshold block 33. The threshold level U _{then is} set so that the threshold block 33 is triggered only by signals coming from the zero direction. When the threshold level is exceeded, the threshold block 33 is activated and generates a constant voltage, which is supplied to the control inputs of the keys 34 and 35, opening them. In the initial state, the keys 34 and 35 are always closed.

The generated PSK signal u ₂ (t) emitted by the microstrip antenna 14 is received by the vibrator antenna 4.1 and is fed to the first input of the mixer 11 through the circulator 3 and the high-frequency amplifier 5, the second input of which is supplied with a high-frequency oscillation u _c (t) (Fig. 4a) from the output of the master oscillator 1 as the voltage of the second local oscillator. At the output of the mixer 11, voltages of combination frequencies are generated. The amplifier 12 is allocated the voltage of the second intermediate (differential) frequency (figure 4, e)

u _CR2 (t-τ) = U _CR2 cos [ω _CR2 (t-τ ₃ ) + φ _to (t-τ ₃ ) + φ _CR2 ], 0≤t≤T _c ,

;Where $${\mathrm{<figure-callout\; id="2"\; label="U\; P\; R"\; filenames="00000006.png"\; state="\{\{state\}\}">U\; </figure-callout>}}_{PR}=\frac{\mathrm{one}}{2}{K}_{\mathrm{one}}{U}_2{U}_{\mathrm{FROM}}$$

;

ω _CR2 = ω _{CR1 -ω C} = ω _G - the second intermediate (difference) frequency;

φ _CR2 = φ _CR1 -φ _with = φ _G ;

- время запаздывания переизлученного сигнала; $${\tau }_s=\frac{2R}{c}$$

- the delay time of the re-emitted signal;

R is the distance to the bombarded bioobject or its remains;

c is the propagation velocity of radio waves,

which through the public key 34 is fed to the input of the differentiator 36 and to the first (information) input of the first phase detector 6. The voltage U _Г (t) is supplied to the second (reference) input of the first phase detector 6 from the second output of the local oscillator 8 through the adjustable delay unit 23. The output of the latter produces the following voltage

u _Г1 (t) = U _Г (t-τ) = U _Г1 cos [ω _Г (t-τ) + φ _Г ],

where τ is the delay time of the block 23 adjustable delay.

The voltage u _pr2 (t-τ ₃ ) from the output of the amplifier 12 of the second intermediate frequency through the public key 34 of the differentiator 36 is supplied to the first input of the multiplier 20, the second input of which is supplied with the voltage u _Г1 (t) from the output of the adjustable delay unit 23. The voltage obtained at the output of the multiplier 20 is passed through a low-pass filter 21, at the output of which a derivative of the correlation function dR (τ) / dτ is formed. The amplifier 22 is designed to maintain the zero value of the derivative of the correlation function and is connected to the output of the low-pass filter 21, acts on the control input of the adjustable delay unit 23 and maintains the delay τ introduced by it equal to zero (τ = 0), which corresponds to the minimum (zero) value of the correlation derivative functions dR (τ) / dτ. The range indicator 24, associated with the scale of the adjustable delay unit 23, allows you to directly read the measured value of the range R to the bombarded bioobject or its remains

. $$R=\frac{c{\tau }_{\mathrm{<figure-callout\; id="2"\; label="s"\; filenames="00000006.png"\; state="\{\{state\}\}">s</figure-callout>}}}{2}$$

.

In this case, the following voltage is supplied to the second input of the first phase detector 6

u _Г1 (t) = u _Г (t-τ _з ) = U _Г cos [ω _Г (t-т _з ) + φ _Г ],

which is used as a reference voltage for synchronously detecting a received signal with phase shift keying at a second intermediate frequency ω _pr2 u _pr2 (t-τ _s ).

At the output of the first phase detector 6, a low-frequency voltage is generated (Fig. 4, g)

u _n (t) = U _n cosφ _k (t), 0≤t≤T _c ,

,Where $$U_n=\frac{\mathrm{one}}{2}{K}_2{U}_{PR2}{U}_g$$

,

To ₂ - the gain of the phase detector, proportional to the modulating code M (t) (Fig.4, g). This voltage, together with the measured range value L, is recorded and analyzed in computer 7.

If the scanning unit is placed on a moving object, then when it moves at the output of the second phase detector 37 and the control voltage generating unit 39, a control voltage appears, the amplitude of which is determined by the degree of deviation of the zero dip of the antenna system 4 from the direction of arrival of the signals, and the polarity by the side of deviation. This voltage acts on the motor 40, connected through a gear 25 to the platform 26, so that the resulting mismatch is eliminated.

A tracking system consisting of a second phase detector 37, a control voltage generating unit 39, a motor 40, a gearbox 25 and a platform 26 on which an antenna system 4 consisting of a vibrator 4.1 and a frame 4.2 antenna is installed is adjusted so that the antenna system’s zero dip 4 (cardioids) always coincides with the direction of arrival of the signals. In this case, the angular movement of the scanning unit during operation is constantly compensated by the corresponding rotation of the platform 26.

The main characteristics of the device for detecting the location of biological objects or their remains include the following:

- transmitter power of the scanning unit, average - not more than 100 mW;

- frequency range - 900 ... 920 MHz;

- detection range - not less than 2000 m;

- the number of code combinations - 2 ³² ... 2 ¹²⁸ ;

- type of emitted signal - harmonic oscillation;

- type of reflected (re-emitted) signal - broadband signal with phase shift keying (signal base B = Δf _c T _c = 200 ... 1000, Δf _c - spectrum width);

- dimensions of the transceiver located on the biological object or its remains - 8 × 15 × 5 mm;

- the service life of the transceiver is not less than 20 years;

- power consumed by the transceiver - 0 W.

Each prospective participant in events that could make this participant potentially affected is at risk and should be equipped with an additional simple, reliable and miniature device (such as a keychain, ring or small medallion), which should not impede the owner’s normal life activity, but should bear You need unique information about this owner.

The second important requirement for this device is the ability to remotely read the information it carries, an unlimited number of times, without any involvement of the owner, and after a long time, for example, after an earthquake. The proposed method and device satisfy these requirements.

From the point of view of detection, complex QPSK signals have energetic and structural secrecy.

The energy secrecy of complex QPSK signals is due to their high compressibility in time or spectrum with optimal processing, which reduces the instantaneous radiated power. As a result, the broadband QPSK signal at the receiving point may be masked by noise and interference. Moreover, the energy of a broadband signal is by no means small; it is simply distributed over the time-frequency domain so that at each point in this region the signal power is less than the power of noise and interference.

The structural secrecy of broadband QPSK signals is caused by a wide variety of their forms and significant ranges of parameter values, which makes it difficult to optimize or at least quasi-optimal processing of broadband QPSK signals of an a priori unknown structure in order to increase the sensitivity of the receiving device.

Broadband FMN signals allow the use of a new type of selection - structural selection. This means that there is a new opportunity to distinguish these signals from other signals and interference operating in the same frequency band and at the same time intervals.

Thus, the proposed method and device in comparison with prototypes and other technical solutions of a similar purpose provide an increase in the accuracy of determining the location of bombarded biological objects or their remains. This is achieved by increasing the accuracy of measuring the range and bearing of buried biological objects or their remains by using the derivative of the correlation function dR (τ) / dτ, vibrator and frame antennas that form a cardioid radiation pattern.

The minimum method of the derivative of the correlation function and the minimum method of the cardioid radiation pattern (passing through zero), along with high accuracy and sensitivity, have another very significant advantage of the zero methods, namely, the amplitudes of the input signals and their fluctuations do not affect the measurement results
