A Practical Method Against Passive Centroid Jamming In Monopulse Radar

Passive centroid jamming is an effective method against conventional monopulse radar. When spatially dispersed decoy is used, the radar antenna will tend to point at the centroid between target and decoy. This paper analyzes the effect of centroid jamming on angle estimation in monopulse radar, and provides for a practical method against this jamming based on multiple targets detection algorithm and a priori knowledge of DOA of the target. Simulation results validate the effectiveness of this method.
