Abstract
The detection of stationary targets under foliage is an extremely difficult problem. A viable solution to this problem involves using low-frequency FOPEN SAR in a change detection mode. The FOPEN SAR gathers a reference image of the area under surveillance before the targets have entered the area. At FOPEN frequencies the energy transmitted by the radar penetrates through the foliage and provides an image of the tree trunks and other stationary man-made objects (buildings, etc.). The SAR then gathers a test image of the area under surveillance; this test image is comprised of the tree trunks and other stationary man-made objects, plus the targets that have entered the scene. Comparing the test and reference images yields a change image of the area; the returns from tree trunks, buildings, and other man-made clutter are significantly cancelled, revealing the targets hidden under the foliage. This paper investigates some phenomenological aspects of FOPEN change detection using SAR imagery from the CARABAS-II VHF radar.
