摘要： 无人作战飞机在进行远距空战时，要在保证自身安全的前提下打击目标。本文针对远距空战攻击占位的复杂约束问题，提出分段求解策略，将攻击占位过程分为规避目标威胁段与低可见接敌攻击段，将占位航迹进行分段规划。针对占位规划两个阶段的不同任务需求，考虑导弹攻击区与雷达反射截面积对攻击和规避的影响，构建相应威胁评价函数；建立各段的约束条件。以威胁评价函数为代价构建最优问题求解框架，分析了hp自适应伪谱法的数学原理与自适应方法。对四种不同初始态势下进行仿真验证，仿真结果表明在不同态势下，生成的攻击占位航迹满足任务需求和约束条件，且平滑可行，证明了分段处理策略的可行性和算法求解的有效性。

Abstract： Unmanned combat aerial vehicle (UCAV) has to attack the target with the precondition of its own safety during the over-the-horizon air combat. For the complicated constraints, a solution strategy of segmenting is submitted.The fighting occupation is divided into two parts, the evading the threat of target and the low observable attacking, so the path can be planned respectively. For the different task needs, with the consideration of the attacking and evading result influenced by missile attacking zone and radar cross section (RCS), the threat evaluation functions and the constraints are constructed. An optimal problem with the cost function based on threat evaluation functions is constructed. The numerical theory and the adaptive method of hp-adaptive pseudaospectral method are analyzed. The simulation results with four types of initial situation show that the planned path can satisfy the task needs and constraints and be smooth and flyable,which proves the feasibility of segmenting and the validity of the algorithm.

Key words： Unmanned combat aerial vehicle (UCAV); Missile attacking zone; Radar cross section (RCS); Path planning; hp-adaptive pseudaospectral method
