Target Detection and Recognition with PHARUS

Abstract

This report describes the possibility of target detection and recognition with PHARUS, a polarimetric c-band airborne SAR. A study is done to several pre-processing, detection and recognition algorithms. Pre-processing is performed to reduce the speckle noise and improve the detection probability. For this study PHARUS data was recorded during the NATO Panel 3 RSG-20 MIMEX trials at Swynnerton (UK) in October 1996, containing a set of stationary military vehicles. Detection turned out to be successful using a combination of a Polarimetric Whitening Filter (PWF) for optimal speckle reduction and an order-statistics CFAR detector. Recognition based on the spatial and polarimetric properties of the detected targets, was not possible because the resolution of PHARUS is insufficient. Because of the good detection performance, PHARUS can be used as a cue for other sensors with a good recognition performance (multi-sensor approach).
