For the weakness of passive radar seeker (PRS), anti-radiation weapons (ARW) could be jammed easily by two decoys with same frequency. Compared with the high complexity of actualization of traditional angle differentiation methods, a method based on Doppler frequency difference (DFD) of received decoys' signals is presented to distinguish jamming decoy sources with the same frequencies, which has low complexity and easily be actualized. Factors that affect DFD are analyzed in detail. Then differentiation region of PRS telling decoys apart is analysed. The simulation results prove that this method can improve the ability of anti-radiation weapon confronting active decoys effectively.
