安装在高速运动载体上的雷达高度表，其地面回波被一宽带多普勒信号所调制。相位编码雷达可以采用一种检测方法实现对该宽带多普勒信号的检测，其结果不但可以指示速度，而且还可以作为速度选通的抗干扰措施。针对一种面目标，在视频上通过仿真手段研究了该检测方法在加噪和不加噪两种情况下的检测结果。

The radar altimeter mounted on high speed vehicle demonstrateswideband doppler modulation characteristic. A detection method will let phased coded radar to detect such wideband doppler signal, whose result not only gives speed information, but also filters ground echo by speed as a anti-jamming measure. It tests this detection method without carrier frequency in the presence of noise and without noise respectively, for one kind of terrain through computer simulation.
