Collaborative Interception of Multiple Missiles Outside the Atmosphere Based on Hit Point Prediction
Based on the mid-flight characteristics of ballistic missiles,a controllable coordinated intercep-tion terminal guidance frame for attack time based on hit point prediction is proposed.By adopting the model of predicting hit points,high-speed targets can be effectively transformed into fixed or low-speed tar-gets.By considering the real-time requirements,a midpoint prediction algorithm based on the combination of simulated annealing and binary method is proposed.The hit point prediction is fairly accurate,the cal-culation speed is fast,the computational load is small,and the reduction of computational burden of missile borne computers is achieved in effectiveness.A"leader follower"structure is applied to solution,the lead missile adopts proportional guidance to quickly approach the predicted midpoint and the remaining flight time of the follower missile is changed by adjusting its own flight trajectory,which makes remaining flight time of follower missile equal to the estimated remaining flight time of the lead missile.The simulation re-sults show that three interceptors in this guidance frame are enabled to hit the target simultaneously.
