Which radar type is optimized for velocity-based tracking?

• A. Pulse radar
• B. Continuous Wave radar
• C. Synthetic Aperture radar
• D. Pulse Doppler radar

Answer: (D)

Velocity-based tracking hinges on detecting how fast a target is moving toward or away from the radar by analyzing the Doppler shift in the returned signal. Pulse Doppler radar combines a pulsed range measurement with Doppler processing, so it can determine both where a target is and how fast it’s moving along the line of sight. This dual capability lets the system update a target’s position and velocity over time and also suppress stationary clutter by filtering out signals without Doppler shift. The other radar types don’t provide this same combination. A plain pulsed radar excels at determining range from the round-trip travel time but lacks robust velocity information without additional processing. Continuous Wave radar measures velocity well through Doppler shift but provides little or no range information, which is essential for tracking a target’s exact location. Synthetic Aperture radar focuses on generating high-resolution images rather than real-time velocity-based tracking. So, the type optimized for velocity-based tracking is the one that delivers direct velocity information via Doppler processing while also providing range data.
