The Radar, which operates with continuous signal (wave) for detecting non-stationary targets , is called Continuous Wave Radar or simply CW Radar. This Radar requires two Antennas. Among which, one Antenna is used for transmitting the signal and the other Antenna is used for receiving the signal.

Principle of Operation. As opposed to pulsed radar systems, continuous wave (CW) radar systems emit electromagnetic radiation at all times . Conventional CW radar cannot measure range because there is no basis for the measurement of the time delay.
Read moreHow does a radar detect frequency?
The reflected radar signal is measured by the radar’s receiver with a change in frequency . That frequency shift is directly related to the motion of the raindrops. When a storm is stationary, the transmitted energy and the reflected energy or “echo” will not change, as shown below.

The fundamental principles of radars are the same at any frequency; however, the technical implementation is widely different. Most radars, in practice, operate between 400 MHz to 36 GHz ; however, there are some notable exceptions.
