How Radar Detectors Work
Radar detectors help drivers find police radar signals. These signals measure vehicle speed using radio waves.
The device alerts drivers when it senses radar waves nearby. This gives drivers time to slow down.
Detecting Police Radar Signals
Police use radar guns that send out radio waves. These waves bounce off cars and return to the radar gun.
Radar detectors pick up these waves by scanning radio frequencies. They can sense X, K, and Ka bands used by police.
- X band is an older radar frequency
- K band is more common today
- Ka band is the newest and hardest to detect
Common Features And Technologies
Radar detectors come with features to improve detection and reduce false alerts. They use special technologies to work well.
Many detectors include GPS to warn about fixed speed cameras. Some filter out signals from automatic doors and other sources.
