This RADAR type is often used in applications where range measurement is not a factor?

Continuous Wave (CW) RADAR is primarily utilized in scenarios where the measurement of distance is not critical. This is because CW RADAR transmits a continuous signal rather than pulses, which means it does not provide the time-of-flight information necessary for calculating range. Instead, CW RADAR is particularly effective for applications such as speed detection, where the frequency shift of the returned signal can be analyzed to determine the velocity of a target. The absence of range measurement capability makes it suitable for situations where the primary focus is on detecting motion or tracking objects without needing to know their exact distances.

In contrast, other RADAR types like Pulse RADAR and Pulse Doppler RADAR utilize pulsed signals to effectively measure range alongside velocity and other parameters. Frequency Modulated Continuous Wave RADAR (FMCW), while it provides both range and velocity information, also involves signal modulation that requires processing for distance calculations. Therefore, Continuous Wave RADAR stands out in its specific application focus, relying on the principle of Doppler effect for tasks where knowing the range is not a factor.
