The basic energy detector still plays an important role in the extended target detection, with the advantage that it does not depend on any prior knowledge of the observed target. However, for the complex extended target model, the detector's performance has not been adequately studied. This paper will focus on the theoretical detection performance of energy detector for the fluctuating extended target...
A coherent Hough method is proposed here to integrate the pulse-train signal. Based on a narrowband echo model, the suggested method implements the coherent integration by compensating the modulated phase terms from pulse to pulse before applying Hough transform. The improved method outperforms standard Hough transform, particularly in a very low SNR environment. The algorithm's performance is analyzed...
