基于被动声学的超声速武器脱靶量解算方法
|
摘要
针对武器试验环境日趋复杂,电磁干扰强,且现有主动雷达体制反舰武器矢量脱靶量测量系统存在易受干扰这一问题,该文提出利用多个声学基阵,通过测量超声速武器飞行过程中产生的激波,获取该武器在不同时刻相对声学基阵的方位,进而采用平面相交求解该武器的矢量脱靶量。仿真计算结果表明,当声学基阵测向误差为1°,弹道偏角为45°时,中靶点解算精度优于1.2 m,航向角和俯仰角解算精度优于0.5°,测量精度满足试验评定要求,可为被试武器性能评定提供有效支撑,具有十分重要的军事意义。
Miss-distance measurement of anti-ship weapon is very important for performance evaluation.Nowadays, weapon tests almost are carried out under complex electromagnetic environment. It causes missdistance measuring system using active radar to be jammed. A new approach using multi-passive-acoustic system is brought forward to solve this question. The shock wave of weapon is survived and is used to obtain the direction between weapon and acoustic sensors. After that, the track of weapon is calculated using plane intersection. The results of simulation show the calculation precision can be used in performance evaluation.
