摘要
动基座发射的飞行器存在精对准和粗对准两种方案,由于粗对准采用提前获取的失准角,时间效应的不确定性导致对准偏差较难获取,不利于制导精度分析。提出了一种基于命中精度评定的飞行器对准方案等效性分析方法,基于置信上界估计方法,通过对飞行器粗对准和精对准子样进行独立评定和对比,在评定准则下验证了两种对准方案的等效性,可有效确定粗对准状态下失准角的时间效应对精度的影响。
There are two schemes of fine alignment and coarse alignment for aircraft launched on moving base.Because the coarse alignment adopts the misalignment angle obtained in advance,the uncertainty of time effect makes it difficult to obtain the alignment deviation,which is not conducive to the analysis of guidance accuracy.In this paper,an equivalence analysis method of aircraft alignment scheme based on hit accuracy evaluation is proposed.Based on the confidence upper bound estimation method,the equivalence of the two alignment schemes is verified under the evaluation criteria by independently evaluating and comparing the sub samples of aircraft coarse alignment and fine alignment,effectively determining the time effect of misalignment angle on accuracy in coarse alignment state.
