What is the ideal RF frequency for most radar speed detection systems?

The ideal RF frequency for most radar speed detection systems is centered around 24 GHz and 34.7 GHz due to their effective balance of range, accuracy, and environmental penetration. These frequencies allow for precise measurement of vehicle speed while minimizing the impact of factors such as atmospheric absorption and interference from other devices.

24 GHz is particularly common in law enforcement speed enforcement radar because it provides a good compromise between detection range and the ability to measure speed effectively in varied conditions. Meanwhile, 34.7 GHz is often utilized for longer-range applications and can offer enhanced target resolution, making it suitable for measuring the speed of moving vehicles under more adverse weather conditions.

The other frequency ranges mentioned either fall outside the optimal range for speed detection or may not provide the same level of effectiveness due to various technical and environmental factors. This makes 24 GHz and 34.7 GHz the preferred choices for radar speed detection systems.
