What is the difference between CW and pulse Doppler radar?
Continuous wave (CW) radar and pulse Doppler radar are two distinct radar systems with different operational principles and applications.
CW radar works by transmitting and receiving electromagnetic waves continuously simultaneously. It continuously emits a continuous wave of radio frequency and measures the frequency shift of the received signal caused by the Doppler effect. CW radar is typically used to measure the speed of moving objects, such as vehicles, and for applications where high range resolution is not critical. It provides continuous measurements but lacks range resolution compared to pulsed radar.
What is the difference between CW and pulsed signal?
Pulse Doppler radar, on the other hand, works by transmitting short radio frequency pulses and then switching to receive mode to listen for the echo reflected from targets. It measures the delay and Doppler shift of received pulses to determine both the range and speed of targets. Pulse Doppler Radar offers higher range resolution compared to CW radar because it transmits short pulses with well-defined durations. It is used in applications requiring precise range and speed measurements, such as weather monitoring, air traffic control and military surveillance.

The difference between CW and pulsed signals lies in their transmission characteristics and applications:
CW signals are continuous, uninterrupted radio frequency waves transmitted and received simultaneously. They are used in radar systems for continuous monitoring of Doppler shifts caused by moving targets. CW signals do not directly provide range information and are primarily used for speed measurements.
Pulsed signals, on the other hand, are short bursts or pulses of radio frequency transmitted intermittently. Pulsed radar sends pulses then listens for echoes reflected from targets. By measuring the delay between transmitting and receiving pulses, pulsed radar determines the range to targets. Pulsed signals are crucial for radar applications requiring precise range measurements and are commonly used in military radar, weather radar and air traffic control systems.
Continuous wave (CW) Doppler radar operates continuously by transmitting and receiving continuous radio frequency signals. It is primarily used for speed measurements and does not directly provide range information.
Pulsed Doppler radar, on the other hand, works by transmitting short pulses of radio frequency signals and then switching to receive mode to detect echoes reflected from targets. It measures both the range and speed of targets by analyzing the delay and Doppler shift of the received pulses. Pulsed Doppler radar offers higher range resolution compared to CW Doppler radar and is widely used in applications such as weather monitoring, air traffic control and military surveillance where precise measurements of range and speed are essential.
