Police officers have used the science of radars to compute the speed of drivers and to help them keep the roads safe for years. However, there are many drivers who have been using radar detectors to keep them from getting caught speeding and paying costly fines as a results of these speeding violations. In spite of the popularity of radars and radar detectors, there are lots of people who still do not understand the science or technology behind them.
The police use radar guns which work by transmitting radio waves from the radar to the target vehicle and wait for them to bounce back. And since radio waves move through the air at the constant speed of light, radars can easily calculate how far away an object is based on how long it takes for that radio signal to return. When an object such as a car is moving, there is a change in the frequency of these radio waves.
Radars then detect this change and convert it into miles per hour that determine the speed of the target. Furthermore, radar guns also use different types of wave bands to determine the speed of the target, including X band, K band, and Ka band. What a radar detector does is alert the driver whenever it detects the presence of radars.
One of the newer technologies that have come along is lasers. Police officers can now use a laser beam to also determine the speed of a vehicle. A laser is nothing more than a concentrated beam of light. These laser radar guns measure the time it takes for an infrared beam of light to leave the gun, reach a car, bounce off and then return back. These units can determine how far away an object is by multiplying this time by the speed of light. Since this type of radar sends out many bursts of light to determine multiple distances, the system can evaluate how fast the car is moving by comparing these samples.
This is a new problem to speeders. The problem is that while laser speed detectors have a much more focused beam and can detect lasers over greater distances, the police laser guns are much more difficult to evade. While modern radar detectors often come equipped with a light-sensitive panel that detects these light beams, the thing is that by the time your detector senses the laser gun, the vehicle is usually already in the sights of the beam.
While the traditional radar detector operates by alerting the driver to the presence of a radar or laser, there are now detectors on the market that also emit a jamming signal. This signal duplicates the original signal from the police radar gun and mixes it with additional radio noise, which will confuse the radar receiver, and thereby prevents the police officer from getting an accurate speed reading.
Some detectors also use a laser jammer, or light emitting diodes (LEDs), that produce a light beam of their own. This beam prevents the receiver from recognizing any reflected light to get a clear reading on the speed of the vehicle.
So now that you have an idea of how these pieces of electronics work, then perhaps you can avoid getting speeding tickets in the future. If speeding tickets have been a problem for you, then you may want to consider buying one of these units. They will pay for themselves in a very short time.
