摘　　要：针对外层空间有源假目标欺骗干扰,提出了一种基于动力学守恒定律的弹道有源假目标鉴别方法。有源假目标由于并不是客观存在的运动实体,不满足动量矩守恒定律和机械能守恒定律,可以利用这种差异进行鉴别。首先从理论上分析了假目标不满足动力学守恒定律,其次推导了动力学常量的方差估计式并设计了鉴别门限,最后仿真试验验证了算法的有效性。Aiming at dealing with exo-atmospheric active decoys deception jamming, A discrimination method is proposed based on dynamics conversation law in the background of missile defense. The true target and jammer are movement entities, follow the conservation law of mechanical energy and the conservation law of moment of momentum. But this is not true for active de- coys, which is the foundation of discrimination. Firstly, theoretical analysis is presented to explain the non-conservation characteristic of active decoys. Secondly, the variance estimation of dynamics constant is derived and the discrimination threshold is designed. Finally, the feasibility and validity of the proposed algorithm is verified by the experimental results.
