You need to act quickly when a radar detector goes off. ![]() The high-sensitivity radar receiver in a radar detector is tuned to pick up extremely low-level signals and alert you that radar is in use. Unlike lidar, the radar signal isn’t as precise at long distances, allowing it to spread well beyond the vehicle being measured. Most of the new radar guns such as the Stalker II and the Kustom Talon use Ka band signals, so if your detector goes off, you know you need to react right away. ![]() K band (K is short for Kurz, which is the German word for short) and Ka (K-above band) radar are less resistant to atmospheric absorption than X band and less effective over long distances. X band radar is prone to interference from automatic door opening systems. X band is the oldest technology and operates between 8 and 12 GHz the K band is between 18 and 27 GHz and the Ka band is between 27 and 40 GHz. In North America, police officers use radar guns that operate in the X, K and Ka band frequency ranges. Radio frequencies that bounce off of an object moving toward the radar gun are reflected at a higher frequency. The digital signal processor in modern radar guns is configured to analyze the changes in the reflected signal very quickly and display a speed reading in less than a second. If an object is moving away from the tennis ball machine, it will take longer for each ball to bounce back, thus representing a decrease in frequency. Radio frequencies that bounce off of an object moving away from the radar gun are reflected at a lower frequency. This increase in return speed represents an increase in frequency. If you start to move the object toward the ball launching machine, the balls bounce back faster and faster as the object approaches the machine. The balls bounce back to the machine and arrive once per second. Imagine that you have a tennis ball machine shooting balls at a stationary object once every second. Radio frequency signals bouncing off a stationary object are reflected to the source at the same frequency. This phenomenon is called a Doppler effect and is the same reason that a car sounds different as it approaches and drives away from you. Unlike lidar and laser guns, the speed measurement is calculated by how much the received signal has changed in frequency after reflecting off the moving object. In simple terms, a radar gun transmits a narrow beam of radio-frequency energy out the front of the gun and looks for that signal to be reflected back to the gun after bouncing off an object. Modern radar guns aren’t quite pocket-sized, but they are easily transportable and can be hand-held or installed permanently in a police vehicle. This relatively simple technology evolved from military applications before World War II, where long-range installations were the size of a medium-size apartment building. Police officers in North America have been using radar guns to catch speeders since 1949. ![]()
