How far is the measurement for Ka-Band at 1000 feet?

• A. 100 Feet
• B. 157 Feet
• C. 200 Feet
• D. 250 Feet

Answer: (B)

In radar technology, particularly when measuring speeds with Ka-Band, the measurement distance refers to the extent of the radar's effective range where it can accurately detect and measure a target's speed. The Ka-Band operates at a higher frequency compared to other radar bands, which allows it to provide more precise measurements over certain distances.

At a distance of 1000 feet, the effective measurement for Ka-Band is approximately 157 feet. This distance is crucial because it defines how much area in front and around a target the radar can accurately track and measure. Knowing this parameter is essential for law enforcement officers using speed measurement devices, as it affects how they determine the speed of vehicles without interference from misreadings caused by other objects or factors in the environment.

Thus, understanding that the effective measurement at 1000 feet is 157 feet assists users in applying this knowledge practically, ensuring accurate readings during speed enforcement operations.
