| 中文摘要: |
| 针对导弹试验环境日趋复杂且大都在复杂电磁干扰环境下进行,现有主动雷达体制反舰导弹矢量脱靶量测量系统存在易受干扰这一问题。本文提出利用多个声学基阵,通过测量超声速导弹飞行过程中产生的激波,获取导弹在不同时刻相对声学基阵的方位,进而采用平面相交求解导弹矢量脱靶量。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1.2m,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,可为被试导弹性能评定提供有效支撑,具有十分重要的军事意义。 |
| 英文摘要: |
| Miss-distance measurement of anti-ship missile is very important for performance evaluation. Nowadays, missile tests almost are carried under complex electromagnetic environment. It leads to miss-distance measuring system using active radar would be jammed. An new approach using multi-passive-acoustic system is brought forward to solve this question. The shock wave of missile is survived and is used to obtain the direction between missile and acoustic sensors. After that, the track of missile is calculated using plane intersection. The results of simulation show the calculation precision can be used in performance evaluation. |
