摘　　要：针对多云天气条件下,云团对激光信号产生较大衰减作用从而影响末制导性能这一问题,提出一种考虑云团对激光衰减作用的滑翔增程激光制导炮弹弹道规划方法。经过合理假设建立云团近似模型,在此基础上设计云团规避—控制能量最优复合规避目标函数(Compound Evasion Objective Function,CEOF)。根据激光导引头工作特性和制导炮弹的飞行特性建立弹道规划模型,采用Radau伪谱法将弹道规划问题转化为非线性规划问题(Non-linear Programming,NLP)。调用NLP求解器SNOPT求解。选取多组云团算例进行仿真分析,仿真结果验证所提弹道规划方法的有效性。研究结果表明,与传统弹道规划方法进行仿真对比,新的弹道规划方法以增加较少动能损耗、控制能量消耗和攻击时长为代价,大幅减少了云团对激光的衰减作用,验证了其优越性。Aiming at the problem that clouds have a great attenuation effect on laser signal and affect the performance of terminal guidance in cloudy weather,a trajectory programming method of gliding extended range laser-guided projectile considering the attenuation effect of clouds on laser is proposed.A cloud approximation model is established based on the reasonable assumption,and an optimal compound evasion objective function(CEOF)of cloud evasion-control energy is designed.A trajectory programming model is established according to the working characteristics of laser seeker and the flight characteristics of guided projectile,and the trajectory programming problem is transformed into a nonlinear programming problem(NLP)by using Radaupseudospectral method.Finally,the NLP solver SNOPT is used to solve the NLP.Several groups of cloud examples are selected for simulation analysis,and the simulated results are used to verify the effectiveness of the proposed trajectory programming method.Compared with the traditional trajectory programming methods,the simulated results show that the trajectory programming method proposed in this paper reduces the attenuation of clouds on laser greatly at the cost of increasing less kinetic energy loss,and controlling energy consumption and attack time,which verifies its superiority.
