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.

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。

When Doppler frequency shift is very low for the very slow speed of a ship drawing alongside, it is rather difficult to detect ship's speed with a general CW Doppler Radar.

由于船舶靠岸速度很低，多普勒频移很小，利用一般连续波多普勒雷达检测船舶靠岸速度，困难较大。

In this process the most complicated, the most significant is the vehicle-borne radar to detect the speed of radar vehicle is leveling.

在这个过程中最繁琐、最影响测定速度的就是车载雷达车的调平。
