1 CW (Continuous Wave Radar)
CW radars which are the simpliest form of radars operate continuously on stable high frequency. It can be used to sdtetct un stationary targets as distance measurement cannot be performed. Velocity information is extracted by Doppler effect caused by motion between target and the radar.
f = doppler frequency λ = wavelength V = target velocity
