摘　　要：C波段雷达高度表是一种基于机/弹载应用的小型、全固态、高可靠脉冲雷达高度表。为了解决脉冲雷达高度表低高度测量问题,采用收发分开双天线工作模式,在设计上采用了诸多先进的电子设计技术和设计理念。设计低高度C波段脉冲雷达高度表系统,较为详细地给出了各子系统的设计实现方法,同时给出了C波段脉冲雷达高度表的距离性能预测和相应的试验验证结果。试验结果证明了所采用技术手段能有效地解决脉冲雷达高度表低高度测量问题。The C band pulse radar altimeter is a state-of-the-art equipment, which possesses the characteristic of all solid state, small size, light weight, high reliability. It can bear bad environments in the sky. It can be installed on any air vehicle to measure the altitude of the vehicle relative to the ground. In order to solve the problem of low altitude measurement, it adopts various advanced electronic techniques and design ideas, such as Electro Magnetic Compatibility（EMC）, Sensitivity Range Control （SRC）, logarithmic amplifier, pulse repetition frequency jitter, low power radiation ＆control, various anti-interference techniques, digital signal processing techniques, etc.. The paper describes the studies about C band pulse radar altimeter for low altitude. The details on all subsystems are given. The maximum detection range is predicted and experimentally validated.
