How Radars & Radar Detectors Work

What is a Radar?

Radar is an acronym for radio detection and ranging. The Average Radar contains a K-Band microwave RF (radio frequency) transmitter whose signal gets reflected by the target object. The reflected signal will have a Doppler shift proportional to the target speed.

This Doppler frequency shift is detected in the receiver, amplified, filtered, and then digitized in an analog-to-digital converter (ADC), and passed onto the digital signal processing (DSP) chip. Using complex algorithms, the DSP chip filters out false and low-level return signals to identify the speed of the desired target. The speed, along with various statistics and averages, is then displayed on the LCD.

How is speed calculated? Speed is calculated using the difference between the transmit frequency and receive frequency (also known as the Doppler shift).

How accurate are Radars?

The Average accurate to within +/-1 mph.

How does the user need to be positioned in relation to the moving object? The Average Radar works best when positioned in front of or behind the moving object.

Can radar guns determine the speed of an object moving in any direction ? No, Doppler radar can only determine the relative speed of targets moving either toward or away from the radar.

Does angle affect accuracy?

A 12-degree angle should not affect performance. The average Radar is accurate to within +/-1 mph for a baseball 75 feet away at an angle of 12 degrees or less. A 20-degree angle at 60 feet away would result in an accuracy of +/-3 mph.

The Radar detector only identifes a radar signal, while a Radar Detector a specially modulated field of light in front of the vehicle to muddle radar and laser gun readings.

These types of Radar Jammers are legal because they transmit light instead of radio frequencies to make your vehicle electronically invisible to police radar and laser guns.
