Which of the following statements regarding the functioning of moving RADAR is correct?

• A. It only measures the target's speed
• B. It requires recalibration every use
• C. It measures the speed of both the target vehicle and the patrol vehicle
• D. It cannot be used while the police vehicle is in motion

Answer: (C)

The correct statement regarding the functioning of moving RADAR is that it measures the speed of both the target vehicle and the patrol vehicle. This feature is essential in radar technology as it allows officers to determine not only how fast another vehicle is traveling but also how fast their own vehicle is moving at that moment. By accounting for both speeds, the radar unit can accurately calculate the target vehicle's speed relative to the moving patrol vehicle. In moving radar systems, the technology uses Doppler shift principles to capture the speed of the target. This dual measurement capability enhances law enforcement's ability to enforce speed limits effectively, especially when both vehicles are in motion. The other statements do not accurately describe the operations of moving RADAR. For example, while the speed measurement of a target vehicle is a primary function, measuring only that speed would limit the device's effectiveness without context of the patrol vehicle's speed. Recalibration typically isn't required after each use; instead, routine checks and calibrations are usually done to ensure accuracy. Finally, moving RADAR systems are specifically designed to operate while the police vehicle is in motion, which allows for more dynamic enforcement of traffic laws.
