Radar Detectors Glen Burnie MD

1. What does a radar detector detect? Most law enforcement agencies use an apparatus that measures the speed of vehicles, usually with a radar or laser. The radar is basically a microwave radio signal that bounces off your car and returns to the gun, the frequency of the return radio wave determines the speed of the vehicle.
   
   Laser or Lidar guns do the same thing but with light beams. Just like the frequency bands in a radio you listen to, there are different bands that radar guns use. The most common are the X band, the K band and the Ka band. The Ka band is used in roughly seventy percent of all radar guns produced today. For you Europeans there is also the Ku band. Laser guns are becoming more and more popular but are still nowhere as prevalent as radar.
   
   Another thing to look for in detection is POP detectors. This is a short burst of radar that some older radar detectors cannot pick up on. There are newer photo radars (speed cameras) which use a weak radar signal and photograph your license plate if they determine you are speeding. Most detectors cannot see or have a hard time seeing these radars but they do make products to shield these cameras from photographing your plate.
