Description

The invention relates to the field of application of individual protection (stealth) of objects based on the formation of a holographic image of a real background without an object from optical-electronic devices of small-sized unmanned aerial vehicles (MBLA), can be used in military equipment.

Various technical solutions are known using a holographic image to provide individual protection of aircraft from missiles equipped with homing heads operating in the frequency range of the visible and infrared radiation spectra. The essence of these inventions is as follows: in the space between the aircraft and the most probable direction of a possible enemy missile attack, a holographic image of a real source emitting electromagnetic waves is formed mainly in the frequency range of the visible and infrared spectrum. As a false target, sources emitting electromagnetic waves at other frequencies corresponding to the operating frequencies of various missile guidance systems for air targets can also be used (patent RU No. 2141094), as well as creating a false target for an approaching rocket by forming a temporary image, including the following stages: the preparation of multiple shells in each channel of one or more barrel assemblies, in which each shell has a body and a back belt attached to the shell of the projectile an explicit seal with the corresponding bore, and in which said projectiles include image forming material for simulating specific target characteristics, a predetermined number of shots from a plurality of shells from selected barrel assemblies, and deploying image forming material to obtain a temporary image and create a false target for approaching rockets (patent RU 2247922).

A disadvantage of the known personal protection systems is the complexity of their implementation and the predominant possibility of use only when protecting against air defense systems controlled by ground-based radar stations. In addition, known systems cannot be used for individual stealth of objects from MBLA equipped with optoelectronic devices.

The invention is the use of a holographic video camera, an analogue of patent RU No. 2464608, shooting the background on which the object is placed, the direction of holographic projection is made using a device for determining spatial coordinates, which are determined by the prototype of patents RU No. 2123165, 126846, the construction of a holographic projection is carried out according to the prototype of the patent RU No. 2323542, FIG. one.

The invention is a method of holographic secrecy of objects from MBLA, works according to the following scheme: electromagnetic radiation 2 from MBLA 1 propagates in the atmosphere, which determines the detection unit and the automated information processing system (BIOASOI) 3 and generates a holographic projection 4 of one background of electromagnetic radiation of the phono-objective environment 5, FIG. one.

The detection unit and the automated information processing system works as follows: (Fig. 2) the electromagnetic radiation from the MBLA is transmitted to the circular cameras 1 and transmitted to the computer 2, where, using the previously developed program for determining geometric changes in the frames of the video sequence for detecting MBLA (certificate of state registration of a computer program No. 201311694), determines the spatial coordinates of the MBLA and transmits information to guidance system 3. Guidance system 3 using electric motors Attic, energized power unit 6 performs guidance constructing holographic projection device 5 towards MBLA. In this case, the holographic video camera 4 from the opposite side (180 °) removes the background-object environment and transfers it to the computer 2, where using the program the object is removed from the frames of the video sequence (filling in the frames of the video sequence of the coordinates of the color of the object with the background color) or replacing it with the one shot in advance , no object background setting. From computer 2, the processed frames of the video sequence are sent to the device for constructing a holographic projection 5, from where they are projected toward MBLA, where a holographic image of the background is formed, thereby hiding objects in the frequency range of the visible spectrum.
