What advancement in RADAR technology occurred in 1972?

• A. Military restrictions were lifted
• B. Radar by law enforcement was introduced
• C. Use of speed measuring devices in moving patrol vehicles
• D. First ground RADAR station was established

Answer: (C)

The advancement in RADAR technology that occurred in 1972 was the introduction of speed measuring devices in moving patrol vehicles. This development made it possible for law enforcement to measure the speed of vehicles while in motion, significantly enhancing the ability to enforce traffic laws and improve road safety. Prior to this advancement, RADAR was primarily used in stationary setups, limiting its application in real-time speed monitoring. The integration of RADAR technology into moving vehicles provided a more dynamic and effective method for traffic enforcement, allowing officers to assess speeds over a wider area and adapt to changing traffic conditions instantly.

The advancements in technology that facilitated this integration required significant improvements in the RADAR systems, including better signal processing and miniaturization of equipment, enabling practical use in patrol cars. This milestone marked a turning point in how traffic law enforcement could be conducted, setting the stage for future developments in speed measurement and monitoring.
