Integration of Elevation Correction with Surface Reflected Wave Removal for Detection of Low Reflective Targets in UAV Mounted GPR Systems

摘要

We present an integration of elevation correction algorithm with Singular Value Decomposition (SVD) based surface reflected wave removal algorithm for ground penetrating radar (GPR) systems positioned above ground with elevation variation. The GPR system and the experimental environment are simulated using the gprMax open-source software. The simulated scenario can be used for GPR mounted on Unmanned Aerial Vehicle (UAV), e.g. drone. The results show excellent reduction of both the effect of terrain with elevation variation and the effect of the surface reflected wave, increasing the probability of object detection, especially when the targets are low-reflective objects. The improved detection capability is tested using Faster-RCNN network, which shows the effectiveness of the method.
