摘要
叙述了线性调频脉冲压缩体制雷达高度表工作原理,介绍了普通脉冲压缩体制雷达高度表在低高度应用中存在的问题和解决途径,实现了脉冲压缩体制雷达高度表从低高度(起飞)到高高度的全程工作,以避免脉压体制和脉冲体制组合使用所带来的系统测高误差.并经机载试验验证,实现了脉冲压缩雷达高度表全高程工作.
Operational principle of radar altimeter with linear frequency-modulated (LFM) and pulse compression is demonstrated, and the issues and its solution of general pulse compression system radar altimeter are introduced at low altitude in practice, pulse compression system radar altimeter is achieved and operated at full altitude from low altitude (start flight) to high altitude in order to avoid the error of altitude tested by system, while using the integrated pulse compression system and pulse system radar altimeter. The altimeter is tested by airplane and achieved the operation at full altitude.
