Method and Device for Detecting Discontinuous Body with Ground Penetrating Radar

摘要

A method and a device for detecting a discontinuous body with ground penetrating radar, comprising acquiring a ground penetrating radar signal of a predefined underground space, where the ground penetrating radar signal carries discontinuous information about an electrical parameter of the underground space; determining, from multiple preset dip angles, a target dip angle of the ground penetrating radar signal with respect to each of multiple channels to be scanned, by a target scanning algorithm; separating the ground penetrating radar signal according to the target dip angle, to obtain a scattered wave; performing velocity continuation analysis on the scattered wave, to obtain a focusing velocity of the scattered wave; and imaging the scattered wave according to the scattered wave and the focusing velocity, to obtain an imaging result, where the imaging result is used to determine distribution information of the discontinuous body in the predefined underground space.
