摘　　要：为了提高捷联式制导迫弹的目标捕获概率和命中精度,研究了其末制导段弹道优化设计问题。根据制导迫弹的工作过程,结合捷联导引头的空间模型,以制导迫弹飞行攻角和飞行时间作为设计变量,建立了包含导引头视场角、弹目距离及终端弹道参数等多约束的弹道优化模型,并采用改进的粒子群优化算法进行求解。仿真结果表明:优化后的弹道能够保证捷联导引头在较高高度探测到目标。研究结果可以为捷联式制导迫弹的工程研制提供依据。In order to improve the target-acquisition-probability and hit-probability of strap-down guided mortars, trajectory optimization of terminal guidance for strap-down guided mortars was researched. According to the the working process of guided mortar and the model of strap-down seeker in space, the attack angle and flight time were taken as design variables, a multi-constraints trajectory optimization mod- el was established and a modified particle swarm optimization algorithm was developed to solve the problem. The simulation results show that the optimal trajectory obtained by modified particle swarm optimization can ensure strap-down seeker to detect targets at higher heights. The results can provide the basis to the engineering development of strap-down guided mortar.
