| 摘 要： | 针对空间平台发射非制导毁伤单元对近程高速非合作目标进行拦截防御的射击诸元快速解算问题,建立了命中方程,并基于命中方程的一阶解,给出了2种解析算法确定发射时刻、发射速度矢量与提前点坐标之间的函数关系.提出了计算命中时刻、发射速度矢量与发射时刻间函数关系的二分数值方法.最后通过仿真分析了算法的方法误差及适用范围.

| Abstract: | The fast fire data calculation of unguided damage cells is investigated,which intercepts a high speed non-cooperative target in short range,and the hitting equation is established.Base on the first order solution of the hitting equation,two analytic solutions for calculating fire time and fire velocity depended on target position are obtained.The numerical algorithm for calculating fire velocity and hitting time depended on fire time is also proposed.Finally,according to the implementation of simulation,the... |
