WIDE-ANGLE RADAR TARGET RECOGNITION WITH SUBCLASS CONCEPT

Abstract

Abstract—The range profile is an easily obtainable and promising feature vector for a real-time radar target recognition system. However, the range profile is highly dependent on the aspect angle of a target. This dependency makes the recognition over a wide angular region difficult. In this paper, we propose a classifier with a subclass concept in order to solve this dependency problem. Recognition results with six aircraft models measured at a compact range facility are presented to show the effectiveness of the proposed classifier over a wide-angular
