CW ( continuous wave ) Doppler radar advantages and disadvantages/ limitations

CW Doppler Radar 

Advantages and disadvantages/ limitations are as following:
1. It can give accurate measurement of relative velocity, using low transmitting powers, simple circuitry,low power consumption and equipment whose size is much smaller than that of comparable pulsed equipment.
2. It can measure a large of target speed quickly and accurately.
3. It is unaffected by the presence of stationary targets.

Disadvantages/ limitations

1. It is limited in the maximum power it transmits .
2. It cannot indicate the range of target ; it can only show its velocity , because the transmitter signal is unmodulated.
