Continuous Wave (CW) radar operates by continuously transmitting a signal and measuring the Doppler shift of the reflected signal to determine the speed of a moving object. Unlike pulse radar, which transmits discrete pulses, CW radar continuously emits waves, making it ideal for speed detection and tracking moving targets. CW radar is often used in automotive radar systems, weather radar, and maritime applications. Its ability to measure the velocity of objects with high precision makes it essential for collision avoidance systems and weather monitoring.
