利用引信多普勒频率估计导弹脱靶量方法研究

针对利用导弹引信多普勒频率数据求取脱靶量的问题,提出了一种非线性最小二乘优化参数估计方法。该方法利用导弹遥测数据独立获取引信多普勒频率数据,因而在无须对测量系统作任何改进的情况下,可得到导弹脱靶量的最优估计。通过对污染数据的野点剔除、补点和逐次逼近,有效地提高了脱靶量的估计精度。给出了应用该方法的具体步骤,通过模拟和实际数据计算证明了该方法的有效性。

Research on estimating missile miss distance using fuze Doppler spectrum

In regard of evaluating miss distance of using missile fuze Doppler spectrum data,a optimizing parameter estimated method of nonlinear least square is put forward.This method can independently obtain fuze Doppler spectrum data using missile telemetering data,thus the optimum estimate of missile miss distance is gained in the condition of no need to improve measuring system.By means of abnormal data deletion,addition data and successive approximation for original data,estimated accuracy of miss distance is improved effectively.Specific steps of the method are given,and the effectiveness is proved by simulation and actual data calculations.
