Radar Detector Buying Guide

Radar and laser detectors are a great way to keep yourself safe while driving. They can help you avoid accidents and detect when drivers are following too closely or speeding. They also make it easier to catch drivers who illegally pass other cars in the fast lane, which is a serious safety concern.

Even though radar detectors are efficient, don’t expect them to work 100% of the time. There are several things that usually interfere with its performance so keep in mind a few things before you start doubting your investment.

First off consider the position of your radar detector. Also, remember that some devices have both front and rear coverage. These are the detectors you need. There is no knowing when a radar you’ve just passed is being pointed at you.

Secondly, look out for radar detectors that send out false alarms. The best ones have all sorts of software destined to remember certain locations and to also isolate signals which are not sent by actual radars or police lasers. We recommend the Escort RedLine Radar Detector when it comes to reducing false alarms.

How to Use a Radar Detector

How does radar work to detect the speed?

The radar releases radio waves at a specific frequency that has the same speed as that of light. These rays travel towards the car and hit it. At this point, they bounce back toward the radar.

If the targeted vehicle is in motion, then the waves that bounce back have a changed frequency. The car moving towards the police radar reflects back to the higher frequency waves.

On the other hand, when the car is moving away from the police cops, then the reflected rays would have the lowest frequency.

The police compare this difference with the initially emitted signal and determine the car’s direction and speed.

How does radar work to detect the distance?

The total time, that the rays take to hit the car and go back to be detected by the radar gives the distance. The difference between the emitted and received rays tells us about the speed of the vehicle.

One point to know,

Only those vehicles which are approaching the radar directly show a very accurate reading of speed. But car direction at an angle with the reference to the radar gives less accurate readings.


It’s time to have an insight into the working of a radar detector. It is easy to understand now because you have the key functioning of the radar.

How to use a radar detector?

We have told you before that radar emits radio waves of a certain frequency that hits the car in its path.

At this point, the actual game starts.

These rays, in the air, are detected by the detectors present in the car. And you get an alert, in the form of the voice of light, about the presence of radar before coming into the eyes of the police. And the driver readily lowers the car’s speed.

The more the range of the radio waves, the earlier the detector will give you an alert.

What is the strategy behind it?

You can consider three basic parts of a radar detector. These are:

  • Receiver
  • Processor
  • Detector

The receiver is in the form of antennas that are present on the front and rear sides of detectors. They receive the radio waves and transfer them to the processor. This part basically analyzes this signal and generates a response.

The response generated is caught by the detector and produces alerts in the form of sound or light, according to the internal setting.

Types of radar detectors

As stated earlier, radar emits signals of different frequencies. So the detector, you are using, should have a working range of these frequencies.

These frequencies are available in the form of bands. Each band has its own frequency. The detector can detect only those signals whose matching frequency band is available in the radar detectors.

Typically, radar uses the following frequency bands:

  • Ku band
  • Ka-band
  • K band
  • X band

The Ku-band frequency is the most uncommon one, which has a frequency value of 13.45 GHz.

Ka is not a single-frequency band. But it has multiple sub-bands in it. These sub-bands are Ka super wide bands, Ka wide band, and the Ka-band. Their frequency range is 34.2 to 35.2 GHz.

K-band uses the frequency range of 24.05 GHz to 24.25 GHz. This is the most common band used by the police radar.

Detect the signal from the 2 to 4 miles. This low-frequency X-band makes detection very easy. In addition to police radar, other devices also use this frequency band.

How do laser detectors work?

Let me tell you that laser radar uses light waves in place of radio waves to detect the speed of cars. These rays fall in the infrared region; hence, have a more wavelength than that of light.

Police use this type of radar because the light waves are not detected by the typical detectors used by most drivers. With the 905nm wavelength and 30 ns pulse, these rays went undetected in most cases.

In this situation, drivers prefer the laser detector or a detector with a dual function, i.e., laser and radio wave detection.

Disadvantages of the laser detector

From the same initial distance, the beam divergence from the laser radar is fairly less than the typical radar. Due to this reason, some rays went undetected by the radar. Police have to focus on the specific point to collect the reading. This is quite frustrating.

Advanced radar detectors

Due to the multiple uses of radar detectors, law administrators have banned their use of radar detectors.

To make it possible, the police have started to use RDDs (Radar Detector Detectors). This device picks the availability of a radar detector by the emitted oscillations from the device.

Companies have introduced advanced type of radar detectors on the market that suppresses these oscillations, which make the RDDs working impossible.

Final Verdict

It seems funny that here begins the hide-and-seek between the police and the drivers. I don’t know what would be the next strategy of the police and law enforcement. We can just wait and watch where would this game is going to end.

The winner will be law enforcement or the radar detector user. It will be decided by the time.

Radar detectors are amazing, but you should know how to use a radar detector. This will, of course, save you from frustration and let you drive in a very cool and worry-free mood.
