摘 要: 常规雷达导引头是通过位标器输出目标视线角速度,对机构实现有着极高的要求。本文提出在雷达导引头设计中利用分离原理把最优跟踪问题分解为最优滤波和最优控制问题,在数据处理中实现最优滤波,而位标器仅用于指向跟踪,从而降低了对位标器机构的指标要求,并提高了跟踪精度。最后利用数值仿真验证了理论的正确性。 Conventionally, line of sight (LOS) angular rate of target is provided by antenna servo of radar seeker, so requirement for the implementation mechanism is very high. In this paper, an optimal target tracking problem is divided into optimal filtering and optimal control problem by using of separation principle. The optimal filtering is achieved in dada processing, while the antenna servo system is only need steering tracking beam against target; therefore requirement for specification of the antenna servo mechanism is reduced, and tracking accuracy got improved. Correctness of the theory proposed is verified through numerical simulation.
