Pulsed Doppler radar provides which measurements?

• A. Range
• B. Velocity
• C. Range, Velocity, and Azimuth/Elevation
• D. All of the above

Answer: (D)

Pulsed Doppler radar determines multiple aspects of a target by combining time-of-flight, Doppler shift, and antenna direction information. The range comes from the time it takes for a emitted pulse to travel to the target and echo back. The velocity is obtained from the Doppler shift of the returned signal, which reflects motion along the line of sight (radial velocity). If the system includes angular measurement capability—such as scanning the beam, using multiple beams, or monopulse processing—it can also resolve the target’s position in azimuth and elevation based on where the beam is pointed and how the returned signal is phased. With these capabilities, the radar can provide range, velocity, and angular coordinates, i.e., all of the above.
