How Do Radar Detectors Work? Some Basic Things to Know

Posted In Technology - By Ryan Stewart On Friday, October 26th, 2018 With 0 Comments

Radar detectors are small devices that will help identify the presence of speed radars, like those used by the police to locate vehicles driving over thespeedlimit. Some kinds of radar detectors detectthe presence of laserspeed guns that are useful for people looking to avoid the speed traps that traditional radar detectors will miss. To know how exactly the radar detector works, it’s very helpful to understandthe basic radar functions.

Understanding the complete feature

You might ask how does radar detector work and given below is your answer.Radar detectors are often used to identify speed and distance, like how far away the object is and how quickly it is moving. The radar device emits radio waves that move with the pace of light and also bounces back to the radar device whenever it encounters any object in the path.

how does radar detector work

  1. When the radar is used for detecting speed, the radio wave frequency is altered from a returned signal because the car is moving. Suppose any vehicle is moving toward theradar device, the return signal has a shorter distance of travel and the radio wave frequency will increase. Radardevices then can use this change in the frequency to know the speed in which a car is moving. In the laserspeed guns, light waves are used instead of radio waves.
  2. The simple radar detector will identify the radar devices that are based on the radio waves it emits. Essentially, the radar detectors act as the radio receivers, taking specific frequencies that are used by the radar devices, particularly radar guns that are used by the police incatching any speedy vehicles.
  3. Other advanced radar detectors will not just detect the police radar, but also throw off the reading that police radarsget. In such kinds of detectors, the radio transmitter emits a scrambled signal (named jamming signal) that takes an original detected signal &adds additional signals. When the scrambled signal reaches the radar, the police will get trouble receiving anaccurate speed reading. The similar system exists in laserspeed guns (lidar) wherein the laser detector emits a scrambled light beam.

Are detectors worth buying?

The radar detectors aren’t very costly. However, they are not generally found in the local shop or a shopping mall. The best method to get a new detector is ordering it on the internet. Before ordering, you must pay close attention to many factors. Firstly, you need to check with the local police department if radar detectors are permitted in your country. Second, ensure that radar detector you want to buy is new and also comes with a warranty. Third, order devices from known companies.
