采用高抛弹道的反临拦截器制导律设计

Guidance Law for Near Space Target Interceptor using Parabolic Trajectory

摘要:

高超声速武器拦截由于相对速度极快，机动能力、速度均不占优势，因此需要进行高精度的中、末制导研究。本文以临近空间高超声速巡航飞行器为拦截对象，提出了采用高抛弹道拦截的设计思路，针对临近空间飞行器的弹道特征和机动性能，设计高抛弹道的初、中、末复合制导律，并对目标进行不同机动模式的拦截效果进行分析，仿真结果表明，基于高抛弹道的拦截器能够有效拦截巡航类高超声速临近空间目标。

Abstract:

Because the relative speed is very fast, the maneuverability and speed are not predominant, hypersonic weapon needs to be studied with high precision mid and terminal guidance。In this paper, the high hypersonic cruise vehicle is taken as an interceptor, the design idea of using parabolic trajectory interception is proposed. In view of the ballistic characteristics and maneuverability of near space vehicle, the initial、 middle and final guidance laws of the parabolic trajectory are designed. The interception effect of different maneuvering modes of the target is analyzed. The simulation results show that the Interceptor based on parabolic trajectory can effectively intercept the near space target of Cruising hypersonic.
