What is stepped frequency radar signal processing?
However, since the stepped-frequency continuous-wave (SFCW) radar works in frequency domain, its working principle is more complex compared to that of e.g. a time-domain based pulsed radar where the desired signal containing the target's reflection peaks is yielded directly by recording the echo of the transmitted ...
How does ground based radar work?
In short, GPR works by sending a radio signal into a structure and reading the “bounce.” The radio wave bounces off any material it encounters and creates a reading that displays those bounces as hyperbolas. An experienced GPR technician interprets this reading to determine the type of material located.
What is the ground penetrating radar procedure?
A GPR transmitter emits pulses of electromagnetic energy into the subsurface. Changes in the sub-surface are detected based on differences in permittivities. When a change in the sub-surface is encountered, some of the electromagnetic energy is reflected back to the surface.
