摘　　要：研究了用于底排/火箭复合增程榴弹射程修正引信的弹道辨识方法以及辨识精度.根据蒙特卡罗模拟理论,选取弹道纵风、初速和弹道系数作为建立随机概率模型的初始参数,生成一条随机弹道模拟实际弹道,根据靶场实测的加速度值,利用弹道辨识方法对实际弹道辨识,比较辨识射程和实际射程,得到弹道辨识方法精度.结果表明,主动段弹道辨识方法误差不大于1%,其弹道辨识精度能满足工程要求.The method and precision of trajectory identification of a range correction fuze based on projectile of compound extended range by base bleed and rocket were studied. Based on the theory of Monte-Carlo simulation, the trajectory wind, initial velocity and trajectory coefficient were taken as the initial parameters in order to formulate the random probability model, by which random trajectory was computed. According to the real acceleration value, the calculated trajectory was identified by the trajectory identification algorithm. The precision of the trajectory identific- aition method were obtained by comparing the ranges of the identified trajectory with the calculated trajectory. The result shows that the error of the trajectory identification algorithm is less than 1%, and the precision can meet engineering request.
