有终点交会角要求的拦截弹拦截导引设计

针对终点处交会角固定的拦截导引问题,基于前人得到的需用速度公式,提出了通过迭代飞行时间来确定能满足交会角要求的需用速度,并在飞行过程中不断修正实际速度使其与需用速度一致的方法.该方法直观、可靠并能满足时空一致性的要求,最后通过仿真验证了其有效性.

Interception Guidance Design for Interceptor with Terminal Aspect Angle Constraint

To design the interception guidance with the terminal aspect angle constraint, based on the formula given by other persons, a new solution was brought out, which main idea was to obtain the needed velocity vector by iterating the flight time; then modify the practical velocity during the flight time until the needed and the practical velocities are almost equivalent. This method is intuitive and reliable, .and it can also guarantee that the target and the interceptor arrive at the same location at the same time. At last, the availability was demonstrated by the simulation example.
