Abstract

The Army Research Laboratory has investigated various phenomenology-based approaches for improving the detection of targets in wide-angle, ultra-wideband foliage penetration synthetic aperture radar (SAR) data. The approach presented here exploits the aspect-dependent reflectivity of vehicles, by filtering the SAR image data to obtain sub-aperture images from the original full-aperture radar image. These images represent the images of the target as seen by the sub-aperture SAR from two different locations (squint angles). We present a straightforward approach to extending an existing collection of features for a quadratic polynomial discriminator with features calculated from these two, lower-resolution sub-aperture SAR data images. We describe a method for generating the modified features and assess their potential contribution to improved probability of detection.
