A complete Guide for Radar Detectors

November 6, 2007

Wide range of electrical devices has been designed by innovative manufacturers. Radar detector is a recent innovation which is very helpful for the motorists. Motorists need the device to find whether their vehicle speed is being noticed by the police people. To find the excessive speed, police use a radio wave which will be bounced on your moving car. With the help of wave’s frequencies police will easily determine the speed of your car.

Wave length bands are essential component to detect signals. These detectors have the ability to alert while you are moving close towards the speed trap. Therefore you can reduce the speed to escape from police. Nowadays a radar emitting gun is preferred by the police. Oncoming vehicles on the road will be aimed by the radar emitting gun. A signal will emit from the gun to your vehicle and reach back to the gun. The time taken to travel from the gun to your vehicle will be calculated to measure the speed. No need to worry about the radar guns because radar detectors have the compatibility to find the presence of the radar gun before it detects your vehicle speed.

Various features have come equipped with Radar Detectors. They are voice recorder and driver alert option. When you have driver alert option, you will be alarmed to prevent from falling in deep sleep during late night travel. The system uses beeps to alert you. Most people do not have any idea about the technology behind the device. Technology used in radars is simple and clear.

PROCESS BEHIND THE DETECTION
As said earlier, radio waves perform an essential role in the functioning of radar detectors. These detectors emit radio waves and it will carefully listen to echo. When any vehicle crosses or comes in the path, these radio waves will reflect electromagnetic energy automatically. Therefore the radio waves will bounce and come back to the radar detector. The radio waves have the potential to move around the air in an unimaginable speed. Thus radar detector detects how far an object by calculating the time taken by the radio signal to reach back.

KINDS OF RADAR DETECTORS

• X-Band
The unique features of X-Band radars are higher power output and lower frequency. These kind of X-Band radars were used in the midst of 1950s. These devices had the potential to detect radio signals from minimum of 2 miles to 4 miles. Accuracy in speed reading can be expected from half mile or less. These X-band radars functioned with the frequency range from 10.5 to 10.55 GHz. As these devices performed with the range of lower frequency, the motorist will be alerted not only for police radars but also for microwave alarm, garage door openers and microwave towers.

• K-Band
These K-Band radars have come with the potential to perform with the frequency range from 24.05 to 24.25. People used these units during the year 1978. These radars with K-Bandwidth were designed as handheld radar guns which had used from vehicles in stationary position. Then they were redesigned as ‘pulsed’ version for moving vehicles. The clocking range of K-Band police radar is about ¼ mile. These radars have the ability to detect signals between the ranges of ¼ mile to maximum of 2 miles.

• Ka Wide-Band
The frequency range of the Wide bandwidth is 34.2 to 35.2 GHz. During 1987 police started to have “photo-cops” which uses automatic camera. If a vehicle comes with an excessive speed, the camera will capture the images of the vehicles. You can get useful details like the front portion of the vehicle, the date, place, time and even the license plate will be shown on the photograph. These devices have come with the ability to take snaps of 200 vehicles per hour. The outstanding range of the photo-cops starts from 120 to 300 feet. Ka Wide-Band radars are used to detect these photo-cops.

• Ka Super Wide-Band
Radars functions within the frequency range of 33.4 to 36.0 GHz are known as “Ka Wide-Band Radars”. After the introduction of photo-cops, stalker guns were used to trigger the vehicle speed. These types of stalker guns have been still used now in half of the UK. As a result, detector manufacturers have developed new radar detectors which perform with the support of “super wide-band technology”.

OTHER CLASSIFICATION OF RADAR DETECTORS
Radar detectors can be classified on the basis of usage of cords instead of frequency bandwidth. Detectors can be classified into:

• Corded Detectors
These corded detectors have been made in such a way to plug into your vehicle’s fuse box or cigarette lighter. Corded detectors are widely popular among the UK people. The installation of corded detector is also easy. The transportability and the potentiality to detect distinct bandwidths are also remarkable.

• Cordless Detectors
If you want to avoid getting mess up by big bunch of cords, it is well and best to prefer cordless detectors. A remarkable benefit of cordless detector is the ability to conserve the life of batteries. You should be ready to sacrifice range as well as sensitivity and range.

• Remote Mounted Detectors
The main drawback of this type of detector is huge cost. They are sold in expensive costs. They require professional assistance to install in your vehicle.

Tips to pick a right Radar Detector
While you decide to buy a radar detector for your vehicle, it is important to keep some essential tips in mind to pick a right radar detector.

• Money is the lifeblood of any purchase. Therefore decide about your budget before you go for shopping.

• Decide about the installation. If you want to accomplish installation through a professional installer, you have to choose a shop which offers such facility. If you are not interested to have such a facility, you can buy a detector from wherever you want to. So that you can install by yourself.

• Always prefer branded units to rectify issues arises in future, if any.

• Prefer a detector which has the stuff to sense wide band.

• Sensitivity is a vital factor to be considered while you choose a detector. If you wish, you can get lab-test results from concerned manufacturer.

• Choose a detector which offers embedded memory. Therefore you need not to adjust every setting while you start every time.

• Get anti-glare display to view clearly though you move during hot sunny days.

• Check additional features like mute option, volume adjustments etc.

• Your driving habit has to be kept in mind while you pick a radar detector in the leading shop in the UK.

Make use of these suggestions and choose an appropriate radar detector to suit your driving habits. Have a panic-free driving!!!
