研究了无人作战飞机（ UCAV）自主对地攻击轨迹规划问题。首先，建立了考虑发动机燃油消耗、飞行约束和武器投射终端约束的多约束模型，研究了UCAV动态雷达威胁问题，建立了随姿态和距离变化的精确雷达探测概率模型；其次，详细分析了HP伪谱法基本理论及其求解最优控制问题策略，利用HP伪谱法并结合对地近距作战实战背景，分别以时间最短、威胁代价最小和定时飞行为目标函数进行雷达规避轨迹规划仿真研究，得到了期望的攻击轨迹并对3条轨迹进行了深入对比分析；最后，对仿真结果进行了精度分析，分析计算表明仿真误差在允许范围内，再次验证了方法的可行性。

The automatic fight trajectory planning for the Uninhabited Combat Aerial Vehicle ( UCAV) in air-to-ground attacking was studied .Firstly,we established a multi-constraint model for UCAV by taking the thrust fuel consumption,flight constraint and weapon shooting terminal constraint into consideration,studied dynamic radar threats for UCAV,and built up a radar detection probability model changed with its posture and position .Then,we analyzed the HP pseudo-spectrum theory and strategy to solve optimal control problem,made simulations for radar-avoiding trajectory planning by taking the minimum time cost ( MT),lowest observable ( LO) probability and constant time ( CT) respectively as the objective function .Three expected trajectories were obtained and analyzed .Precision analysis was made to the simulation results,and the calculation results show that simulation error is kept in the allowed range ,which proves the feasibility of the proposed algorithm .
