摘　　要：为优化简易制导火箭弹的控制能力,提高其对目标的打击精度,提出一种基于单导引头和侧向测量装置多弹协同末制导的方案,应用高斯伪谱法弹道规划理论,对协同系统内每枚火箭弹的打击路径进行优化。设计相应的控制系统,在保证协同系统测量和控制的位置要求的前提下,使得火箭弹沿着规划路径飞行,实现了多弹协同制导与控制。对协同末制导方案进行仿真验证,所提方案能很好地实现多弹协同末制导,且对目标有较高的打击精度。Adding a seeker device to a simple guided rocket,so that it has terminal guidance capability and can improve its strike accuracy.However,adding a seeker to each rocket will greatly increase the cost of the weapon system,and due to the weak control capability of the simple guided rocket,it will affect the accuracy of its attack on the target.A multi-bomb cooperative terminal guidance scheme based on a single seeker and measuring device is proposed.Using Gauss pseudo-spectral trajectory planning theory,the strike path of each rocket in the cooperative system is optimized.The corresponding control system is designed so that the rocket missiles can fly along the planned path,and the position requirements of the measurement and control system are ensured,and the multi-bomb cooperative guidance and control is realized.The simulation analysis of the cooperative terminal guidance scheme shows that the proposed scheme can better realize the multi-bomb coordinated terminal guidance and has higher strike accuracy.
