Four-Channel Monopulse Technique for Main-lobe Interference Suppression

since the accuracy of acquisition and guidance radar is threatened by main-lobe interference, a technique of four-channel monopulse for main-lobe interference suppression is presented. A delta delta channel is added based on traditional there-channel monopoles, which is used to cancel main-lobe interference. The technique we present significantly improves the detectability in the presence of main-lobe interference. The simulation and analysis in the article testify that the technique is effective and realizable.
