被动测向精度试验异点剔除方法研究

Research on the Method of ELiminating Outliers in Passive Direction Finding Accuracy Test

对侦察设备测向误差验收试验时异点产生的原因进行了分析,同时对异点必须剔除的理由进行了研究。对莱以特检验法、格罗布斯检验法等常用的剔除方法优缺点进行了比较,得出一次莱以特检验法为侦察设备测向误差验收试验最优剔除方法,同时根据该验收试验的需要,推导出侦察设备测向误差异点剔除的工程简化方法。利用Matlab软件工具,采用大样本数字仿真方式,分析了该方法剔除异点在不同条件下产生的负面影响,验证了该剔除异点方法的风险可控。

This paper analyses the causes of outliers in the direction finding error acceptance test of reconnaissance equipment,and studies the reasons why outliers must be eliminated.The advantages and disadvantages of common eliminating methods such as Leyte test and Grobbs test are compared,and the optimal eliminating method for reconnaissance direction finding error acceptance test is obtained.At the same time,according to the needs of the acceptance test,the engineering simplified method for eliminating outliers of reconnaissance direction finding error is deduced.By using the software tool of Matlab and using the method of large sample digital simulation,the negative effects of eliminating outliers under different conditions are analyzed,and the risk of eliminating outliers is controllable.
