Imaging Process Based on Bistatic Scanning for Subsurface Radar

概要

A subsurface radar system is assumed as monostatic radar configuration due to its imaging process, although the radar is not monostatic configuration but bistatic one. The aim of this research is to reconstruct an image based on a bistatic radar configuration model. A back projection histogram method (BPHM) has been proposed as novel imaging process. By this method, an image can be reconstructed from reflected wave signal obtained by bistatic radar configuration, though it is imposible by conventional method. First, a bistatic scanning method is described for imaging process, then a quasi-multistatic scanning is also proposed as the method to be equivalent to scanning of multistatic radar configuration. The last, experiments of steel plate detection are demonstrated to present a effectiveness of proposed scannning and BPHM. As the result, inclination angles of buried steel plate are detected by proposed method more precisely than conventional method.
