摘要
介绍了比例导引法的导引规律,推导了基于比例导引规律的拦截弹弹道方程.给出了一种目标做正弦机动飞行的轨道方程,并采用Matlab对拦截弹拦截目标进行了目标拦截仿真.分析了拦截弹速度和目标速度,以及导引系数对拦截弹弹道的影响,研究了导弹实际飞行中弹道曲率与法向过载的关系.
Proportional guidance law is introduced, and trajectory equation of intercepting missile based on proportional guidance law is deduced. A kind of orbit equation of target in sine mobility is given, and the missile intercepting the target is simulated with Matlab. The influence of missile speed, target speed and guidance mode on the trajectory is analyzed. The relationship between trajectory curvature and normal over-loading is researched.
