针对纯方位运动目标分析问题，建立了带乘性噪声的状态空间模型，推导出了在线性最小方差意义下的目标状态最优递推估计算法，并通过算法的误差分析讨论了模型的各种随机干扰的统计参数及估计算法初值的选取．
Aimed at the problem of purely azimuth moving target analysis, a state space model with multiplicative noise is established, and the optimal target recursive estimation algorithm in the sense of linear minimum variance is deduced. The error analysis of the algorithm is used to discuss various models Statistical Parameters of Random Interference and Selection of Initial Value of Estimation Algorithm.
