Design of an Optimal Predictable Midcourse Guidance Law to Intercept the High-speed Maneuvering Target

In this paper, to study the midcourse guidance method of intercepting the high-speed and large maneuvering targets, the concept of predicted handover point is proposed, and corresponding mathematical model is established. Then based on the optimum control theory, a predictable midcourse guidance law with the optimal performance at handover time is put forward, and the predictive interception proportional guidance item is introduced to correct the guidance law when the target is maneuvering. The simulation shows that this guidance law has good midcourse guidance performance and can meet hand-over conditions between midcourse guidance and terminal guidance.
