摘　　要：有源诱偏系统是地面雷达抗反辐射导弹(ARM)攻击的主要措施之一,由于诱偏过程中诱饵无法获知ARM的实时位置,且ARM存在惯性导航误差,因此,现有诱偏系统的诱偏效果具有不可靠性。针对这一问题,提出一种基于单站定位原理的单机动诱饵抗ARM方法。在机动有源诱偏原理的基础上,给出雷达发射机关机后诱偏系统对ARM的定位方式,推导定位方式的系统误差;同时综合考虑惯性导航误差,分析ARM可能落点区域,进而确定恰当的诱饵关机时间,提高诱偏系统的可靠性。仿真实验结果表明:诱偏系统可对ARM实施有效定位,并且控制诱饵实现成功诱偏,有效保障了雷达和诱饵的安全。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.
