radar doppler shift的意思|示意

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 paper, an integrated optical modulator is proposed and analyzed, which is constructed in a fin line geometry and can be applied to a Doppler radar for processing the Doppler frequency shift.

提出并分析了集成电光波导调制器在多普勒雷达中的一种新的应用方式。该调制器的电极采用鳍线结构，能够方便地获取多普勒频移信号。
