面向突防的多约束滑翔弹道优化设计

快速通过敌方雷达探测区域能够增加打击突然性,提高突防性能。如何在弹道设计中描述雷达探测问题是必须解决的问题。为此,在常见多约束条件下的弹道设计方法基础上,根据雷达方程,将辐射型禁飞区约束转化为沿弹道积分的威胁系数约束。基于威胁系数积分建立弹道优化性能指标函数,利用hp 自适应Radau伪谱法对此优化问题进行求解,得到了满足飞行过程约束且暴露于敌方雷达探测区域最小的飞行弹道,对比分析仿真结果,验证了模型和方法的正确性,达到了提高突防性能的目。

Multi-constraints glide trajectory design optimization toward penetration

It will improve the penetration performance for boost-glide vehicles by passing the radial zone quickly. How to describe the radial zone is a problem that must be solved in trajectory design. Based on the common multi-constraints trajectory design methods, the constraint of the radial no-fly zone is transformed to the threat coefficient constraint along the trajectory integral according to the radar equation. The cost function is given based on the integral of threat coefficient. The hp-adaptive Radau pseudo-spectral method is used to solve this optimization problem. A minimum threat trajectory satisfying process constraints and exposed to radial zone minimum is achieved. The threat model and this method are both proved to be right through comparing and analyzing the simulation results. The aim to improve the penetration performance is achieved.
