针对网络瞄准攻击对战斗机精确引导的需求,研究威胁规避下的战斗机攻击引导轨迹优化问题。以战斗机过载为控制量建立引导状态模型；以目标威胁建立引导路径约束模型；以导弹发射瞄准条件为终端约束；以引导的快速性和控制经济性为性能指标,将轨迹优化建模为具有非线性边界约束、状态约束和路径约束的最优控制问题,并采用高斯伪谱法将其转化为非线性规划问题进行求解,为了保证算法的实时性,采用滚动时域策略进行在线滚动优化。仿真结果表明：所提出的方法能在有效规避目标威胁下达成导弹攻击的瞄准条件,基于RHC策略的优化单次计算时间小于1 s,算法实时性能满足战斗机的引导需求。

A new guidance algorithm with threat avoidance ability and target sighting restraint is proposed for traditional staged guidance method lack of threat avoidance ability.Firstly,mathematic model of guid-ance is established based on relative velocity vector,second,the path restraint model is established based on threat avoidance,and guidance terminal restraint for target sighting is given.Value function is estab-lished based on rapidity,economical control and guiding precise,optimal control model for attack guidance is constructed with nonlinear boundary restraint,state restraint and path restraint.Gauss Pseudo spectral Method (GPM)is adopted to transform the problem into nonlinear programming problem.Simulation re-sult shows,this new guidance algorithm is effectively for threat avoidance and the missile launch require-ment is well satisfied by air combat requirement.
