文中阐述了雷达高度表的测高原理和脉冲雷达高度表的工作流程,提出了导弹高度控制回路的工作原理和设计方案,并对高度表阈值与导弹飞行速度、导引头视场等因素的关系进行了仿真分析.仿真结果表明,为了保证弹道平稳,高度表阈值应增大;而当飞行速度较大时,应减小高度表阈值;在导引头视场角不变的前提下,减小高度表阈值也能够避免障碍物对导引头视线的遮挡,有助于捕获目标.

The principle of radar altimeter and the working procedure of pulse radio altimeter were described in this thesis. The principle and design scheme of missile altitude control loop was put forward. The simulation and analyze was carried out to validate the relations between threshold of altimeter and the velocity and view-area of missile. The simulation shows that the threshold should be increased for stabilization of trajectory and be reduced when missile velocity is correspondingly big;If the view-area angle of seeker is changeless,the reducibility of the threshold of altimeter will avoid that remora keeps out the LOS of seeker.This helps to capture the target.
