本文论述了战略导弹制导系统精度评估方法，并分析了影响制导精度的各种因素；在定性分析的基础上，建立了制导系统的误差模型，并将此模型归纳为线性回归模型；最后，对目前所采用的误差分离方法进行了分析和比较，并将模型参考自适应思想与岭估计方法相结合，形成了模型参考自适应广义岭估计方法，为解决制导系统误差分离问题提供了一条有效途径。
In this paper, the methods of evaluating the precision of the guided missile guidance system are discussed, and the various factors that affect the guidance accuracy are analyzed. Based on the qualitative analysis, the error model of the guidance system is established, and the model is summarized as the linear regression model. Finally, At present, the methods of error separation are analyzed and compared, and the model reference adaptive method and ridge estimation method are combined to form a model reference adaptive generalized ridge estimation method, which provides an effective way to solve the error separation problem of guidance system .
