Advantages: Highly flexible, can be programmed to recognize different objects, not just range and velocity. Sensors can be low cost. Mm-wave FMCW radars can have very high resolution for ranging, velocity and imaging application. A distance measurement resolution of 2 cm can be easily achieved over 20-30 meters.

What are the advantages and limitations of CW radar?
The CW radar can measure the Doppler frequency of the target, but it cannot measure the target range. The frequency-modulated CW radar (FM–CW) can measure both the range and Doppler frequency of the target. In the FM–CW radar, the transmitted frequency changed as a function of time in a known manner.

Drawbacks or disadvantages of FMCW Radar
➨They are used for targets at very short ranges. This is due to use of lower peak output power. ➨Due to use of lower transmit power, the signal gets attenuated and affected due to atmosphere and channel before it is received by the receiver.
What is the major disadvantage of CW radar how to overcome it?
One of the greatest shortcomings of the simple CW radar is its inability to obtain a measurement of range. This limitation can be overcome by modulating the CW carrier, as in the frequency-modulated radar.
