Which radar measurement distance corresponds to K-Band at 12 degrees?

• A. 200 Feet
• B. 210 Feet
• C. 220 Feet
• D. 230 Feet

Answer: (B)

The correct distance measurement for K-Band radar at a 12-degree angle is 210 feet. This value is based on the characteristics of radar waves and their ability to accurately measure speed over a specific distance at different angles.

K-Band radar operates in the frequency range that allows it to effectively transmit and receive signals over various distances. At a 12-degree angle, 210 feet is determined to be the optimal distance for obtaining reliable speed measurements. This angle and distance combination helps to minimize errors that can occur due to factors such as the Doppler effect or the geometry of the radar waves interacting with moving vehicles.

Understanding the correct distance in relation to the angle of the radar can impact the precision of speed enforcement measures. In the context of speed measurement practices, radar distance calculations are crucial for determining how radar equipment should be deployed and how to interpret the data collected.
