针对不同防御阵地位置与防御半径,利用Radau伪谱法进行了机动再入飞行器最短时间突防轨迹的优化研究,分析发现,随着防御半径的增加,飞行器依靠空气动力进行侧向机动规避较难实现,并且当防御阵地靠近目标点时,飞行器可机动规避的范围较小,但由于其飞行高度的特殊变化,使得地面防御力量仍然难以实施有效拦截。计算结论对再入飞行器突防轨迹的设计以及地面防御力量的部署都具有一定的参考价值。
According to the positions and defensive radii of different defensive positions, Radau pseudospectral method was used to optimize the penetration and defeat trajectory of the maneuver reentry vehicle. It was found that with the increase of the defensive radius, it was more difficult for the aircraft to rely on aerodynamic lateral maneuver And when the defensive position approaches the target point, the scope of the aircraft maneuver avoidance is small, but because of the special changes in the flight altitude, it is still difficult for the ground defensive forces to implement effective interception. The conclusion of the calculation is of certain reference value for the design of the penetration trajectory of the reentry vehicle and the deployment of ground defense forces.
