An Efficient Correction Method of Direction Finding in Phased Array Reconnaissance System

Abstract

This paper deals with the direction finding problem in the phased array electronic reconnaissance system. With practical application scenarios, an approximate correction method is proposed for the azimuth error of the amplitude comparison method, and the correction method is optimized continuously in combination with the characteristics of the multi-beam reconnaissance task. This method only needs to obtain the elevation of the task, the result of conventional direction finding, and the correction coefficient of each beam which are delivered with the task message. In the simulation section, a series of experiments are proposed to evaluate the effectiveness of the correction method.
