Compared with a conventional single-channel GPR system, a GPR system with a multi-input and multioutput (MIMO) antenna array is not only more efficient in 3D data acquisition, but also allows the collection of a multi-offset dataset, thereby providing additional information for more effective subsurface imaging. We develop a three-dimensional (3-D) reverse time migration (RTM) algorithm for processing...
Airborne ground penetrating radar (GPR) can be used for detecting underground targets in dangerous area or area covered by heavy vegetation. Since the back projection (BP) imaging method can easily compensate for the electromagnetic wave's refraction effect, it can be a practical imaging method for airborne GPR system. Nevertheless, the conventional BP imaging method usually suffers from high computational...
GPR is a nondestructive detection method which has been widely applied to detect defects in concrete structures. In field geotechnical engineering cases, it is very hard to observe anomalies caused by longitudinal defects using ground-based GPR detection, which produces great difficulties in data processing and interpretation. Compared with the traditional ground-based GPR, the cross-hole GPR can...
Ground penetrating radar (GPR) velocity tomography has shown much promise in the detection of geological hazardous bodies. Using GPR velocity tomography technology, faults parallel to the transmission direction can be more accurately detected than faults perpendicular to transmission direction. This indicates that ray coverage has a great influence on inversion accuracy. In order to identify accurately...
