An Improved Borehole Radar Fusion-Imaging Method for Heterogeneous Subsurface Sensing

In this paper, a heterogeneous borehole radar fusion-before-imaging method (RFBI) is proposed and validated. Different from traditional fusion methods, RFBI firstly fuses radar sample sets from heterogeneous radar systems (such as monostatic, bistatic and multi-input multi-output) and then do imaging process once in high-dimensional space to obtain imaging result with high accuracy. Specifically, ...
