If it is unsafe, speeding is a matter of driving, and most people are guilty of that. Most sprinters are quite satisfied with the idea of ​​excessive speed, which they do unconsciously. On roads where there are few policemen, speed drivers can get used to this habit, but this is changing in an environment where they run the risk of being arrested. Nothing makes an ordinary sprinter as uncomfortable (or challenging) as a ticket. Nothing makes buying a radar detector more attractive to them.

How do police and civil radar detectors work?

The radar gun, uncovered to the simplest elements, can be described as a receiver-transmitter device, which can be used to measure the speed of an object. Like all Doppler radios, radar emits an electromagnetic wave. A wave is reflected from any object it points to. The waves that are reflected from a radar gun are called “echoes” and are analyzed by the device. The radar gun can determine the speed of the vehicle by the nature of the echo that is reflected in it.

civil radar detectors

The electromagnetic wave that the gun emits can be detected, and that is how radar detectors work and how they were invented. Radar detectors detect the signal from a radar gun and warn the driver to slow down to avoid ticking.

Now, if everything stopped at this moment, everything would be simple, but then the drivers, chasing the wheel, will get away with it and the speed limit will be useless. So, no, it did not stop what should be called an arms technology race. To get around the radar detectors, each of them has become smarter. Of the police, the frequency of the radar became lower. The time it took to discover how fast the driver was driving became shorter. On the driver’s side, radar detectors have been able to better recognize low-level signals that have been sent for a shorter period of time. The police also introduced devices that can determine if the driver uses a radar detector. The civil radar detectors also started turning on the detectors of these devices so that the main detector could be turned off and, therefore, not be detected.


This is the next step in determining speed and uses light instead of radar waves to determine the speed at which the vehicle is moving. The range is smaller and the devices more expensive, so most police officers still have a minimum Doppler version. Devices already used for LIDAR wedging devices.
