摘要
根据弹道导弹的中段飞行特性,提出了一种基于命中点预测的攻击时间可控协同拦截末制导结构.采用预测命中点的模式,能够有效地将高速目标转化为固定或低速目标.考虑到实时性要求,提出了一种基于模拟退火与二分法结合的命中点预测算法,命中点预测较为准确,计算快速且计算量小,能够有效降低弹载计算机的计算负担.采用了"领弹-从弹"结构,领弹采用比例导引快速接近预测命中点,从弹通过调整自身的飞行弹道来改变剩余飞行时间,使之与领弹的估计剩余飞行时间相等.仿真结果表明,该制导结构能够使三枚拦截器同时击中目标.
Abstract
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.
