Study of the deception effect of radar equipped with decoys

Purpose - The purpose of this paper is to provide a solution to investigate the deception effects of the radar equipped with decoys. Design/methodology/approach - Since the attacking process of the anti-radiation missile (ARM is very complicated, numerical simulations are used here to analyze the effects of the operating parameters and the layout parameters of the radar and the decoys on the survival probabilities. Findings - The survival probabilities of all the radar and the decoys can be over 99.5 percent when three decoys distribute near the radar in an appropriate way and the decoy level is set to some appropriate values. Research limitations/implications - The movement model of the ARM is simple and should be improved further. Practical implications - The numerical results may be applied directly in practice and the dynamic simulation algorithms may be as a reference of the radar-decoy technique in the future works. Originality/value - Some coordinate systems are built. Based on it, the models of the radar and decoys against an ARM are introduced, including the fields radiated by the radar and the decoys, the guidance signal and the movement of the ARM. Numerical simulations have been performed here. Some conclusions have been given.
