Advantages continuous wave RADAR : 1.Single frequency transmission and hence narrow receiver bandwidth 2.Duty cycle is unity, so mean power can be as high as transmitters will permits. 3.Ability to see moving targets in presence of large number of echoes from stationary target to which it is blind. 4.Target velocity can be measured using Doppler shift. 5.Zero minimum range. 6.Simple to design and construct. 

Disadvantages of continuous wave RADAR 1.No timing marks, so unable to measure range. 2.Separate antennas are required for receiver and transmitter. 3.Cannot detect targets crossing its beam at right angles.
