Title:
DETECTION METHOD AND DEVICE FOR GROUND-PENETRATING RADAR DISCONTINUUM
Document Type and Number:
WIPO Patent Application WO/2018/086222
Kind Code:
A1
Abstract:
A detection method and device for ground-penetrating radar discontinuum, comprising: obtaining ground-penetrating radar signals of a preset underground space, the ground-penetrating radar signals carrying discontinuous information of electrical parameters of the underground space; determining, by a target scanning algorithm, a target inclination angle of the ground-penetrating radar signals with respect to each of multiple channels to be scanned in multiple preset inclination angles; separating the ground-penetrating radar signals according to the target inclination angle to obtain a scattered wave; performing speed continuation analysis on the scattered wave to obtain a focusing speed of the scattered wave; and imaging the scattered wave according to the scattered wave and the focusing speed to obtain an imaging result, the imaging result being used for determining distribution information of discontinuum in the preset underground space.
