导弹飞行试验外测系统误差的估计

The Estimation of Exterior Ballistic Measuring System Error for Missile Flight Test

在导弹飞行试验中,遥外测数据是进行精度和可靠性分析的依据。通常假定外测误差服从零均值正态分布,而在实际测量中,外测参数有可能带有系统误差,它的存在对飞行轨道和落点信息的获取都具有不利的影响。在一定的模型假设下,本文获得了外测系统误差的估计,并对一些仿真结果进行了初步分析。

For missile flight test, telemetering data and exterior ballistic measuring data arethe basis of precision and reliability analysis. Usually, we assume that exterior ballisticmeasuring error has normal distribution with zero mean. But during the real measuring,it is possible for exterior ballistic measuring parameters to cause system error. It has badinfluence on the information obtained from flight trajectory and fall point. With the giv-en model hypothesis, the estimation of exterior ballistic measuring system error is ob-tained in this paper. Futher more, some simulating results and their preliminary analysisare given.
