一种弹道拦截的HP滑模制导律

为了解决拦截器导引头探测由于高速作战引起的干扰问题,一种新的拦截制导方法HP(Head Pursuit)制导正逐步发展起来,这种导引方法是将拦截器导引到目标轨道的前方进行拦截,要求拦截器的速度低于目标的速度,因此可以消除拦截器的气动加热问题,从而降低对拦截器探测设备的要求.在分析了目标和拦截器的运动学模型的基础上,提出了HP导引律的设计方案.并且根据滑模变结构控制具有鲁棒性的特点,设计了HP滑模变结构制导律,通过拦截器拦截目标弹道数字仿真,验证了制导律的正确性.

A Guidance Law of HP Using the Sliding Mode Approach For Ballistic Trajectory Interception

A new guidance law of HP is developed recently to eliminate the perturbation of interceptor detection induced by high speed.The guidance law guides the interceptor missile ahead of the target on its flight trajectory,and the speed of interceptor is required to be lower than that of target.Such guidance relaxes the requirements from the interceptor seeker dome since it is not exposed to the high areodynamic heating.The scenario of guidance law is given,considering the kinematics of the interceptor and the ta...
