A speed radar trap is an electronic device that uses radio waves to detect the speed and acceleration of moving objects. It’s widely used by law enforcement for radar speed traps and is frequently used in professional sport, for things like the measurement of cricket speeds in cricket, the estimation of bowler speeds in football, and the estimation of tennis swings in tennis tournaments. It can also be used to detect the speed and direction of oncoming vehicles in a highway. The main component of most speed traps is a radar gun. Although it may seem a little strange to hunt down people using radar, the fact is that this technology has been around for years and has been successfully used by law enforcement for decades.
Radar Speed Traps
There are two different kinds of radar detection methods. The first involves a radar gun tracking the speed limit of the suspect vehicle. If it detects a violation – say over the speed limit – the signal is captured, read and stored. If the signal shows no violation, the device records the vehicle’s details, including the speed and direction of movement. This information is later sent to a central control unit, which sends the information to a remote-operating centre, which can either act on it or pass it on to the police.
The second kind of radar detection system works with a network of radar sensors. When the vehicle passes into a certain “hot spot” the signal is read and stored. Then it’s compared with a list of known radar-sensitive vehicles that radiate the same speed. If the comparison proves that the vehicle is not one of them, the system is not activated. If it turns out that it is, the speed traps are set to trigger.
