内弹道异常判决中的实时野值剔除方法

摘要

The outliers in the telemetry parameters affect the result of internal trajectory fault. Aimed at the characteristics of telemetry parameters,this paper researched the polynomial interpolation smoothing algorithm method which can eliminate one or more contiguous outliers. At last the result of test data processing show the effectiveness of this method.%任务中导弹遥测关键参数的野值严重影响内弹道的异常判决结果.针对遥测关键参数的变化特点,研究了基于多项式插值平滑算法的野值剔除方法.通过任务实测数据验证,这一算法简单,实时性强,可以剔除连续的野值,在内弹道异常判决系统中起到了获得较好的预处理效果.
