How Radar Detectors Work

There are many drivers who want to know how radar detectors work? We'll Radar detectors are designed to look for radar signals being admitted from police radars. The police radar guns admit a series of radar pulses that can calculate the speed of a car by how long the radar pulses take to return back to the radar gun after they bounce off the car. The radar detector searches for these pulses and attempts to intercept them even before they bounce off the targeted car. Radar detectors use a technology called Superheterodyne design that allows detectors to detect pulses around corners, and over hills. The range can also extend straight ahead.


All radar detectors should have the ability to locate different types of radars. Due to low frequency and high power output, the X-band radar is very easy to detect. Depending on the area, humidity and temperature, the detection of radar can vary from 2 to 4 miles. X-band radar can accurately read speeds from a distance of a half mile or less. Any farther and the reading may be incorrect. Radar detectors can also give off false alarms due to the fact that microwave towers, Garage door openers, and other equipment posses X-band signals.


Most police radar today uses K-band technology. This radar has small wavelength. It's clocking range is most effective at 1/4 of a mile to 2 miles depending on the area the weather and other factors. This type of radar would be late in detecting police radar. A speeding driver would have already been clocked.


Another method in how radar detectors work is the Ka Photo Cop and the Ka wide-band. These radars are set for a predetermined speed that activates the camera When the car approaches it at that speed. A picture of the cars license plate, and driver's face, date, location and time will be taken. Once the pictures are developed speeders will have their tickets mailed to them. These radars can clock and photograph at least 200 vehicles per hour. The range of these cameras is 120 to 3000 feet and they constantly transmit a signal. This can make them easily detected by vehicle radar detectors. Which is a plus for us speeders.


Now the Ka super wide-band is a stalker radar gun With the capability of FCC licensing of any frequency in the Ka-band between 33.4 GHz to 36.0 Ghz. Therefore this technology cannot be detected by radar detectors that only detect X,K and photo radar. Laser radar is more accurate at identifying a particular vehicle and the clocking time is only half a second and is accurate up to 1 1/2 miles. Whats bad about laser radar guns is that they are expensive, do not work behind glass, can only be used standing still, and the person using them must have a very steady hand.


Jamming signals


Conventional radar detectors are designed to pick up police radar. But more sophisticated radar detectors are designed to scramble and jam police radar. These type of detectors play an aggressive part in escaping detection by means of emitting a jamming signal. The signal copies the original signal from the police radar gun, but also mixes it with additional radio noise. This causes the police radar to get a confusing echo signal resulting in inaccurate speed readings.


Some radar detectors posses a light-sensitive panel that can detect lidar gun beams. These devices are extremely difficult to evade, due to the fact that lidar beams are much more focused and doesn't carry all that well over long distances. Vehicles are usually in the beams sights long before the detector can pick up its presence. Some speeders use laser jammers that work the same way as radar jammers.

It is most important to remember that none of these devices are a 100% full proof. Knowing how radar detectors work will give you an advantage when driving on the road. The best and most efficient way to avoid getting a ticket is to just simply slow down.
