Main-Lobe Jamming Suppression Method In Multiple-Radar System

This paper presents a main-lobe jamming suppression method in multiple-radar system. According to the differences in spatial diversity characteristics between target echoes and received jamming, a new feature domain, named amplitude ratio feature domain, is constructed to suppress jamming while retaining targets. Then, a constant false alarm detector is given to detect targets in the constructed feature domain. The simulations verify its jamming suppression ability and the improvement in target detection performance.
