摘　　要：基于无人机对地自动攻击过程,应用最小值原理求解了无人机对地自动攻击占位段的应飞轨迹,该方法将威胁模型、飞机运动方程和对地攻击任务有机结合,使生成的占位轨迹既能有效规避各种威胁又能为武器投放创造条件。对占位轨迹计算中的两点边值问题采用了共轭梯度法求解。通过实例仿真表明该方法是正确有效的,所得占位轨迹波动平缓没有剧烈折线现象,对占位机动研究具有一定的参考价值。This paper presents a basic process of the UAV automatically carrying out a air2 ground strike. Appling minimum theory to compute the maneuvering trajectory before the attack. The threat model, vehicle kinematics equation and the strike mission constraints are integrated into the algorithm so that the resulted trajectory can automatically avoid threat and create conditions to release weapon. The conjugate gradient algorithm is applied to calculate the differential equations of two- point boundary value question. In the end, the result of simulation shows that the method is feasible and has reference value in researching battle motion.
