摘　　要：针对滑翔制导炮弹在不可避免的威胁区域内选择突防方案的问题,从量化威胁值的角度建立了敌方防御手段的数学模型,基于模型设计了全程综合威胁值最低的规划指标,提出考虑目标防御威胁的弹道规划方法。为实现滑翔制导炮弹全程飞行过程中初始弹道倾角、偏角、火箭点火时刻、滑翔启控时刻等各参数的最佳匹配,建立了多阶段全弹道规划模型,并采用hp自适应伪谱法将最优控制问题转换为非线性规划问题求解。通过仿真验证了在该指标下滑翔制导炮弹对目标防御的规避效果,分析了影响有效性的因素。与传统弹道规划方法进行对比,证明了所提方法的优越性。Aiming at the problem of gliding-guided projectile penetration schemes in inevitable threat areas,mathematical models of the enemy’s defense are established from the perspective of quantifying the threat value.Based on the model,a cost function with the lowest comprehensive threat value in the whole process is designed.To accomplish the best possible matching of the initial trajectory inclination,deflection angle,rocket ignition time,gliding start time,and other parameters over the course of the flight,a multi-stage full trajectory planning model is created.Then,the hp adaptive pseudo-spectral method is used to transform the optimal control problem into a nonlinear programming problem.The evading effect of the projectile on target defense is verified by simulation,and the factors affecting the effectiveness are analyzed.The proposed method’s advantages over conventional trajectory programming techniques are also examined.
