基于实测光电跟踪仪误差的分布检验及应用

Error Distribution Test and Application Based on Measured Opto-electronic Tracker Data

对光电跟踪仪跟踪误差特性分析是进行精度试验数据分析处理的前提基础。为了研究光电跟踪仪对空中目标角跟踪测量误差的分布规律,综合采用偏峰度联合检验即Jarque-Bera法和Kolmogorov-Smirnov非参数统计方法,对实测误差数据进行分布检验。检测结果表明光电跟踪仪角度测量误差中远端区段符合正态分布,近区测量误差80%航次不符合正态分布。所得结论为光电跟踪仪精度试验设计和数据处理算法的确定提供了科学依据。

Analyzing tracking error character of opto-electronic tracker is the basic work for precision experiment data processing. In order to hold measurement error distribution law of opto-electronic tracker during tracking air target,Jarque-Bera method and Kolmogorov_Smirnov method are proposed to test measured error data distribution.Test results indicate that angle measure error accord with the normal distribution in middle-long range,however,about 80 percent of flight tracks do not follow normal distribution in near range,which has certain guidance in accuracy test design and data processing algorithm determining.
