Abstract

Land contamination by unexploded mines is a serous problem in many countries. Although a large portion of these mines is plastic, the problem caused by unexploded metallic mines is serious enough to warrant a cleanup effort. These metallic mines may be detected using either a proximity or a standoff sensor. This article discusses the detection of metallic miens using a standoff ultra-wideband SAR sensor. In particular, it analyzes the expected RCS of metallic mines, and the T/C as functions of frequency, depression angle, and soil. The bases of the analysis are theoretical RCS models, an empirical clutter model of bare soil, and limited soil and ground penetrating SAR measurements. The analysis indicates that the SAR should operate in the UHF band, and that the preferred environments are dry soil and possibly frozen soil and snow. Under these conditions, the results indicate that the detection of surface metallic antitank mines should be robust, that the detection of buried metallic antitank mines is viable, and that the detection of metallic anti-personnel mines may be viable with ultrahigh resolution SAR. The false alarm issue is not addressed in this article.
