Radar Detector :: essays research papers

Nowadays, speed-detection technology has become more and more advanced, and not getting a speeding ticket is almost unavoidable. There are a lot of devices around that can help drivers detect the police traps, but these devices are illegal in many states. As people are driving down the interstate with their cruise control set over the speed limit, many get scared of a police car parked on the side of the road. Right after they pass the trap they look at the speedometer and their rear mirror, hoping that the cop will pass them by and go after those whose speed was higher. Now, Rocky Mountain Radar Co. offers drivers a solution to escape getting the ticket. This device is called the Phazer. The Phazer makes your vehicle electronically invisible to the police speed-detecting equipment. It mixes a portion of the radar signals with background clutter and bounces it back to the squad car by way of wave guide antenna, which effectively confuses the computer inside the radar gun. Police radar takes five to ten speed measurements per second of the vehicle. The Phazer sends two different signals to the radar, so the final result is that police radar can not verify the speed of the vehicle and displays no speed at all.  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The Phazer also protects your vehicle from Lidar guns which use distance over time to detect the speed of the vehicle. The Phazer sends an invisible infared signals to the Lidar gun, this way the measurement of the speed is blocked. Many devices like that were outlawed because they transmit scrambling radar beams to the police car. The Phazer reflects only part of the signal and also mixes it with an FM signal. It is perfectly legal for people living in all states but California, Minnesota, Oklahoma, Virginia, and Washington D.C. The Phazer starts to scramble the signals from three miles away from the speed trap.
