	Radar Gun - Picture - MSN Encarta
		Radar guns are used to detect speeding motorists.
		Reflected waves (shown in red) return to the gun at a different frequency, depending on how fast the car being tracked is moving.
		A device in the gun compares the transmission frequency to the received frequency to determine the speed of the car.

	Howstuffworks "How Radar Detectors Work"
		Radar is the use of radio waves to detect and monitor various objects.
		When the car is moving away from the radar gun, the second segment of the signal has to travel a greater distance to reach the car than the first segment of the signal.
		If the radar gun determines that the target is not moving toward or away from the police car, than the target is driving at exactly 50 miles per hour.

	Radar Detectors - Consumer Search Reports
		Police radar guns work by emitting a microwave pulse to measure the speed of a moving vehicle; radar detectors work by sending out a signal that mixes with this pulse to produce a lower, more easily detected frequency.
		Newer radar guns are licensed to operate in any of three frequencies on the Ka-band (33.8GHz, 34.7GHz and 35.5GHz) and are now the most common type of radar gun in use.
		Radar detectors "leak" a low-frequency signal that's detectable by radar detector detectors, such as the VG-2 and Spectre III units used by police.

		Radar is an acronym for radio detection and ranging.
		For months I was looking for a radar gun that was less than $500, and I finally found it.
		You may have to slightly change the angle of the gun to track the pitch, which can be slightly tricky.

	How do Radar Detectors work?
		Radar gun's used by law enforcement share common frequencies of Radar that they use to measure the speed of your vehicle.
		When the officer's radar gun is detected, it sounds a warning signal and flashes lights.
		Radar detectors are currently illegal in passenger vehicles in Virginia and Washington, DC.

	AVE - Radar Gun Interfacing (Site not responding. Last check: 2007-10-22)
		Speed radar guns are primarily used in law enforcement to detect the speed of a passing vehicle.
		When the radar gun outputs this format, it can be directly connected to the text inserter and no other fl box is required.
		Since the radar gun interface merely taps the electronic data, it is impossible for any interface to affect the gun calibration.

	Support for Whistler Radar Detector - Whistler Radar Laser Detector (Site not responding. Last check: 2007-10-22)
		The gun shines the laser beam at an angle across the road and registers the speed of any car that passes by (the system makes a mathematical adjustment to account for the angle of view).
		Radar guns have a cone or dish-shaped antenna that concentrates the radio signal, but the electromagnetic wave quickly spreads out over a wide area.
		The radar gun is configured so that it only monitors the speed of a particular target, not everything in the vicinity, so chances are a detector will pick up the radio signal well before the radar gun recognizes the car.

	Speed Radar Defeater
		Five minutes later, that same radar gun might have warmed up and is now oscillating at 1.500001000 (a change much larger than the final measured difference) but it would still be precise because BOTH the retained and reflected signals would have been shifted identically.
		Some radar guns meant for use in moving Police cars are also connected with the Police car's speedometer, to automatically adjust the output reading to the correct value for the target vehicle.
		Since the circuitry in a radar gun only processes the difference of the frequencies of the retained and reflected signals, the exact same result would be shown whether a target vehicle is moving toward or away from the police radar gun.

	Radar Guns FAQ (Frequently Asked Questions about Radarguns)
		Doppler radar uses the fact the return echo from a moving target (vehicles, baseballs, hockey pucks, golf balls, etc.) is frequency shifted (off the transmit frequency) proportional to the target speed.
		The less the radar is directly in front of or directly behind the target object, the lower the measured speed (the Cosine Effect).
		Radar units may be used, under FCC Rules and Regulations Part 90, by anyone with a legitimate need to measure the speed of objects or vehicles.

	The Basic Radar Gun (Police Traffic Radar Handbook)
		The basic microwave traffic radar is an unmodulated CW (continuous wave) transmitter that illuminates a target to measure the Doppler shift of target reflections.
		Moving radar requires a minimum patrol car speed (typically a few to 20 mph); same-lane mode also requires a minimum speed difference between target and patrol car (typically a few to 5 mph).
		Most radars display the speed of the target with the strongest echo (usually the closest target); some radars have the option to display the fastest (or a faster) target, not necessarily the strongest echo.

	Howstuffworks "How does a laser speed gun work to measure a car's speed?"
		A laser speed gun shoots a very short burst of infrared laser light and then waits for it to reflect off the vehicle.
		The gun counts the number of nanoseconds it takes for the round trip, and by dividing by 2 it can calculate the distance to the car.
		The advantage of a laser speed gun (for the police anyway) is that the size of the "cone" of light that the gun emits is very small, even at a range like 1,000 feet (300 meters).

	Radar Detectors
		The radar component works simply by mixing an X, K, or KA radar signal with a FM “chirp” and bouncing it back at the police radar by way of a wave-guided antenna, effectively confusing the computer inside the radar gun.
		Radar: When the Phazer receives the radar signal, it mixes the signal with an FM chirp than reflects it back to the radar where the added chirp confuses the computer inside the radar gun.
		Use of a radar detector is recommended to alert you to the presence of police radar.
