Processing of Wide-Angle Synthetic Aperture Radar Signals for Detection ofObscured Ground Targets

摘要

This thesis investigates advanced processing techniques for the detection ofradar targets in the presence of clutter. It is assumed that the radar data available consist of multi-aspect angle, fully polarimetric Synthetic Aperture Radar (SAR) images. Various techniques are introduced and tested on available SAR data. These techniques attempt to exploit the multi-aspect angles in order to extract target characteristics not available in any single image. SAR images are manipulated in such a way to decrease the probability of false alarms in the target detection process. Target detection performance of the techniques is presented and compared. The techniques are shown to give superior results than that of regular SAR.
