摘　　要：介绍了高炮射击效果实时评价系统脱靶距离测量的物理原理及数学处理模型;分析了脱靶距离测量误差产生的根源,即弹丸形状、尺寸等的差异,特别是弹丸飞行中的章动现象.对测量误差的修正主要是对N波时间宽度TF的修正.利用角度法和时差法建立修正模型.当弹道线与航路飞行轨迹线相交时,模型的建立是严格成立的.利用试验数据对两种模型的修正精度进行了对比分析,结果表明,选定时差法进行修正,提高了系统的测试精度.The operating principle and the mathematic model of testing the miss distance by a real-time evaluation system for anti-airplane firing effect are presented. The error sources of testing miss distance are analyzed, which include pill-figure difference, pill-size difference, and especially the nutation phenomenon of flying pills. Revision of test error is implemented by revising the time width of N wave. By means of angle and time-difference methods, the authors creatively built the revision model which is satisfied strictly when the ballistic line intersects the fairway track. The revising precision of the two models is analyzed respectively and the results show that the revising formula with time-difference method can improve the system＇s precision.
