The trial which detects a long cable-shaped laying underground thing by turning the ground probe radar

摘要

It knows that it has a directional character for the general ground probe radar which used the butterfly antenna. This means that when we detect a long cable-shaped laying thing, we can get the power signal twice in one turn. Per the conformation, I took data and carried out signal processing. As I predicted it, the following result could get it. An empty can was near wave shape in one cycle while the signal of two cycles could get the metal pipe. FFT was effective in the distinction.
