What type of radar is best suited for tracking fast-moving objects?

Pulse-Doppler radar is specifically designed to effectively track fast-moving objects. This type of radar combines the principles of pulsed radar with the Doppler effect, allowing it to differentiate between various targets based on their speed and movement. The Doppler effect enables the radar to measure the change in frequency of the returned signal, which is crucial when attempting to determine the velocity of moving objects.

In applications where fast-moving targets, such as aircraft or vehicles, need to be accurately tracked, Pulse-Doppler radar can provide real-time information on speed and direction. This capability is vital in air traffic control, missile guidance, and law enforcement speed detection. Other types of radar, while useful in different contexts, may not offer the same level of precision in tracking high-speed movements. For instance, pulsed radar is good for distance measurement but lacks the capability to track speed as effectively as Pulse-Doppler radar. Continuous wave radar operates differently by providing constant waves rather than pulses, which may limit its function in detecting varying speeds. Frequency-modulated radar is typically used for specific applications like ground mapping and may not be optimized for fast-moving target tracking.
