Abstract: Coherent dual point sources are widely used in angular deception jamming for mono-pulse radar. With the cooperation of active jamming systems, radar beam of defence system can be effectively pulled off from target, and the aim of target penetration will be achieved. According to the principle of dual point sources angular jamming, fully polarization echoes of angular deception false targets formed by coherent dual point sources, is derived theoretically. Based on the difference of radar echoes of false target and physical targets, a novel binary hypothesis testing method for discriminating angular deception false targets from others is presented. Theoretical analysis and simulations indicate that the method is valid and feasible.
