Nonparametric detection of radar target in nonhomogeneous environments

Abstract

This paper is devoted to the performance evaluation of the Generalized Sign(GS), Trimmed Generalized Sign(TGS), Modified Savage(MS), Mann-Whitney(MW) and a new proposed detector in multiple target situations. The analysis is carried out for both fluctuating and nonfluctuating received signals. The simulation results show that the new proposed detector has the best detection performance in homogeneous as well as nonhomogeneous background conditions, while TGS procedure is better than the GS detector in distinguishing the primary target from the secondary interfering ones.
