Abstract:
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.

Claim (Index 4):
The method according to  claim 3 , wherein the step of performing velocity continuation analysis on the scattered wave to obtain a focusing velocity of the scattered wave comprises:\n migrating the scattered wave by using a Kirchhoff migration algorithm, to obtain an initial migration result; substituting a time variable in the initial migration result with a first variable, to obtain a transformed initial migration result, wherein the time variable and the first variable are in a relationship b=t 2 , where b represents the first variable and t represents the time variable; applying fast Fourier transform to the first variable and a second variable in the transformed initial migration result, to obtain a fast Fourier transform migration result; calculating a product of the fast Fourier transform migration result and a continuation factor, to obtain migration velocity continuation data; applying fast Fourier inverse transform to the migration velocity continuation data, and substituting the first variable in the migration velocity continuation data after the inverse transform with the time variable, to obtain a plurality of migrated objects, wherein the time variable and the first variable are in a relationship t=\u221a{square root over (b)}; and selecting a target migrated object from the plurality of migrated objects and taking as the focusing velocity a migration velocity corresponding to the target migrated object, wherein the target migrated object is a migrated object having a maximal energy among the plurality of migrated objects.
