Range Distributed Floating Target Detection in Sea Clutter via Feature-Based Detector

Abstract

We investigate the detection of range distributed floating target in sea clutter that consists of stationary speckle modulated by nonstationary texture. With the elimination of the nonstationary part of sea clutter, here a feature-based detector using the consistency factor of speckle is proposed. Experimental results of IPIX radar data sets show that the proposed feature-based detector achieves the better detection performance in comparison with other methods. The nonstationary property of sea clutter has a negative effect on the probability of detection, thus warrant consideration in designing the detector.
