摘　　要：针对需要个体间通讯的多弹协同中制导方法存在抗干扰能力差、通讯延迟高等问题,提出一种基于多弹协同航迹规划的协同中制导方法。考虑导弹侧向过载、敌方威胁以及时空协同等约束条件,采用飞行全程的平均速度考量时间协同性,建立定速与变速两种协同方式,基于离散化的航迹点建立多弹协同中制导航迹规划数学模型;改进多种群粒子群算法,构造协同代价函数,计算协同航迹规划代价值,并更新全局最优解。设置定时与不定时两种条件进行仿真分析,结果表明基于协同航迹规划的协同中制导方法性能良好,规划航迹符合协同中制导任务要求。Aiming at the problems of high communication delay and poor anti-interference ability in the current midcourse guidance methods for multi-missile collaborative operations requiring inter missile communication,a collaborative midcourse guidance method based on multi missile collaborative route planning is proposed.Considering the constraints such as missile lateral overload,enemy threat and spatiotemporal coordination,using the average speed throughout the flight to consider time synergy and establishing two collaborative modes of constant speed and variable speed,a mathematical model of route planning for collaborative midcourse guidance is established based on track points.Multi-population particle swarm optimization algorithm is improved,and collaborative cost function is constructed to calculate the cost function value of collaborative route planning and to update the global optimal solution.Set two simulation environments,timed and untimed,the results show that the collaborative mid guidance method based on collaborative trajectory planning has good performance and the planned trajectory can meet the requirements of the collaborative mid guidance task.
