摘　　要：主要研究了雷达跟踪误差对指令制导系统制导精度的影响。首先对雷达跟踪误差进行建模分析,建立了引入雷达跟踪误差的指令制导回路模型,并得到了简化模型的解析解,根据解析解分析了雷达跟踪误差引起的脱靶量随时间的变化关系;其次运用伴随法详细研究了复杂的指令制导回路模型,并通过仿真得到了制导系统中各环节参数取值变化时,雷达跟踪误差的随机误差引起的脱靶量随时间的变化情况。结果表明:在一定范围内,雷达跟踪误差引起的指令制导系统脱靶量随制导时间的增加而增大,且其系统误差是影响脱靶量的主要因素。The influence of radar tracking error on the miss distance of the command guided system is studied.Firstly,the radar tracking error is modeled and analyzed.The command guidance loop model with introducing of radar tracking error is established,and the analytical solution of the simplified model is obtained,according to which the relationship between the time and the miss distance caused by radar tracking error is analyzed.Secondly,the complex instruction guidance loop model is studied in detail by using the adjoint method,and the change of miss distance caused by the random error of radar tracking error with the time when the parameter value of each link in the guidance system changes is obtained through simulation.The result shows that:the miss distance of the command guided system caused by radar tracking error increases with the increase of guidance time;and the systematic error is the main factor affecting the miss distance within limits.
