雷达测量系统误差的残差诊断方法

A Residual Error Diagnosing Method for System Error of Radar Measurement

针对在MISTRAM系统测量中经常可能在某些测元上出现较大系统误差的问题 ,提出了一种在雷达测量中用于识别系统误差项的残差诊断方法。其基本思路是依次去掉每个测元 ,联合其它测元求解目标参数 ,得到模型的残差 ,通过分析残差的特性可识别系统误差项。实际计算表明 。

In this paper, we present a method to diagnose system error in data from radar tracking. In MISTRAM system, a proper system error model is required to get high accuracy trajectory. Based on the diagnose theory of regression, we study carefully the application in error diagnosing. Simulation and actual measured data processing show that our method can find the data with problem, thus improve accuracy of trajectory.\;
