Abstract: The active decoying system is one of the main measures for ground-based radar against anti-radiation missile (ARM). The decoying effect of the existing decoying system is unreliable since the decoy cannot obtain the real-time position information of ARM in the decoying process, and ARM has inertial navigation error. A new method of single-maneuvering decoy against ARM based on single station location is proposed to solve the problem above. The method of the decoying system positioning ARM after the shutdown of radar transmitter is proposed based on the maneuvering active decoying principle, and the systematic error of the positioning method is deduced. The possible landing area of ARM is analyzed in the comprehensive consideration of the inertial navigation error, and then the appropriate shutdown time of the decoy is determined to improve the reliability of the decoying system. The numerically simulated results show that the decoying system can effectively locate ARM and successfully control the bait to decoy ARM, which effectively guarantees the safety of radar and decoys.
