摘　　要：提出采用外测弹道、靶船GPS定位系统航迹和航向估算脱靶量的事后处理方法。根据导弹是否掠过靶船艏艉线正上方为中靶判定的前提,将靶船简化为艏艉线,确定导弹外测弹道与艏艉线的交会点作为过靶点,对应时刻为过靶时刻。同时,结合遥测综控机高度表参数的突变特征,验证过靶判定结论。实际计算表明:该方法满足反舰导弹试验要求,可做出准确的中靶判定结论,给出合理可靠的脱靶量估算结果。The post-processing method using external ballistics,target ship's GPS track and heading to estimate the miss distance is proposed.According to whether the missile is at the top of the fore and aft line across the target ship is the premise of the target determination,the target ship is simplified as the bow and stern lines,the intersection point of a missile tracking trajectory and the fore and aft line as a target,the corresponding time for the target time.At the same time,combined with the abrupt change of telemetry altimeter parameters,the conclusion of the over target is verified.The actual calculation shows that the method meets the requirements of anti-ship missile test,and can make accurate conclusion of the target determination and give a reasonable and reliable estimation result of the miss distance.
