What is the difference between CW and pulsed radar?

The most common type of radar signal consists of a repetitive train of short-duration pulses . The figure shows a simple representation of a sine-wave pulse that might be generated by the transmitter of a medium-range radar designed for aircraft detection.

Benefits or advantages of Pulsed Radar ➨It can measure range and velocity in the presence of multiple targets . ➨It offers higher S/N ratio. ➨Medium PRF pulsed radar offers better range accuracy and range resolution. ➨It offers better performance for airborne low speed targets.

Pulsed signals remain powered for short periods of time, working with and without some form of modulation, such as amplitude, frequency, or phase modulation. CW signals remain on constantly and may be modulated to function as radars or in communications systems.
