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。
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.
本文介绍了一种X波段低成本、结构简单、小型化的连续波多普勒雷达，雷达前端采用微波混合集成电路(mic)。
An X band low cost, simple and compact continuous wave Doppler radar is presented. The whole front end is designed using hybrid microwave integrated circuits (mic).
对于使用高脉冲重复频率的主动多普勒雷达导引头，连续波近似法不仅计算相对简单，而且可以给出较高的计算精度。
For a Doppler radar homing seeker with high pulse repetition frequency, the continuous wave approximation is not only simple, but also has a high calculation accuracy.
