Imagine that you're tooling up the highway when a little red sports car zooms past. A couple miles farther down the road, you see the same sports car parked along the side of the road with a highway patrol car behind it. How in the world did the cop know that the car had been exceeding the speed limit? The chances are good that the officer used a Doppler radar. If you'd prefer not to meet the same fate, you might want to mount and use a car radar detector.
A brief history of car radar detectors
An Ohio driver by the name of Dale Smith was ticketed for speeding in 1968. Feeling that he was unfairly accused of driving too fast, Smith went to work inventing the first car radar detector. Called the Fuzzbuster, the detection device changed the cat-and-mouse game between traffic enforcement and drivers. Five decades later, Smith's invention for sniffing out police radar is part of a multi-million dollar industry that boasts dozens of manufacturers who sell millions of radar detectors every year.
In the late 1970s, Cincinnati driver James Jaeger took apart and reversed engineered a Fuzzbuster to invent a car radar detector he dubbed the Escort. A couple of years later, Cincinnati Microwave debuted a mini-detector called the Passport. In the 21st century, the vehicle radar detector market is booming with a range of stand-alone detectors as well as radar detectors with scrambling capability.
What is police radar
The radar speed detectors used by many police departments utilize Doppler technology to catch speeding motorists. Doppler evaluates speed by rapidly searching for a shift in blue or red light. The principal works are similar to detection methods used by astronomers who wish to measure the distance and velocity of far-away stars.
How it works
A Doppler radio antenna emits a light beam within the radio frequency range. When the light bounces off a target, it returns to the antenna where speed is noted on the body of the unit. Target velocity changes the frequency of the antenna signal. Cone-shaped police radar beams measure three critical factors:
When a traffic officer reads a radar, all he sees is a number. The radar doesn't tell him which car is speeding. That's why police officers are trained to ensure that their observations match the car they pull over. If they didn't do that, many innocent people would be pulled over and ticketed every day.
When shopping for a car radar detector, be sure to inquire about range. Why? Because a radar detection device is only as good as its range. If all other features are comparable, go for the car radar device with the farthest range.
