A Method of Angle Estimation with Monopulse under Mainlobe Jamming
摘要
Abstract
This paper is concerned with angle estimation under mainlobe jamming using monopulse method for two⁃dimension dig⁃ital array radar.Sum beam and difference beam are formed for azimuth and elevation respectively,using Mainlobe Cancellation ( MLC) technique by adding a double⁃difference channel. The mainlobe jamming is suppressed by nulling the sum and difference beam while preserving the monopulse ratio. The simulation results show that it has a high accuracy of angle estimation under mainlobe jamming. What’ s more,the accuracy is related to the SNR and the directions of the target and the jamming.关键词
