This paper discusses the principle and form of Heterodyne-CWDoppler fuze and Toothed-FM fuze firstly.
本论文首先分析了外差式连续波多普勒引信及锯齿波调频测距引信的原理和系统组成。

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 CWDoppler 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。

This paper expouds the characteristics of quasi-continuous wave(CW) radar, and compares the pulse Doppler radar with CW radar and quasi-CW radar.
