Radar detectors don't "use" any frequencies. However they listen to certain frequencies known as bands(K, Ka, X, Ku). These bands are the frequencies allocated to radar guns to operate on.
Doppler Radar uses the Doppler effect to determine speed toward or away from the Radar. When a Radar return has a higher frequency than the transmitted pulse, the object is coming closer, and the *difference in frequency determines speed. Lower frequency- object is moving away. This is used by police, and for weather Radar to help detect not only speed but to detect patterns characteristic of tornadoes. Also used for other applications not just military. You are your own Doppler system using audible frequencies. You can tell when a car, plane, or train is approaching vs moving away.
That depends on the particular radar system. A simple speed radar used by law enforcement can simply be held and pointed at a target to determine the speed of the target. A more complex system like an air traffic control radar system would have display consoles for the radar operator to view the data.
Radar systems usually use wavelengths and are associated with digital signal processing. They consist of a transmitter, antenna receiver, switch, data recorder, processor, and display. Radar systems are used to track things including weather.
Radar communication is electronic communication without the use of wires. Radar communication can be between a ground terminal, like a cell tower, and a satellite. Or it can be between ground towers and also between two or more satellites.
A radar mast is a high platform to mount a radar antenna such as the radar has an unobstructed view.

A cobra detector is a radar detector. Radar detectors work the same way a radio receiver does. The radar detector looks for frequencies that a radar gun uses.
Radar detectors are legal to use in Nevada, but as you stated they are illegal to sell.
Radar detectors are legal for passenger vehicles in North Carolina. However, they are prohibited for use in commercial vehicles. It is important to note that while radar detectors are legal, the use of radar jammers is illegal in North Carolina and throughout the United States. Radar detectors are devices that can detect radar signals emitted by police radar guns, while radar jammers are devices designed to interfere with or block radar signals.
Radar detectors are legal to use for all non-commercial vehicles in 49 states. Washington, DC and Virginia are the only two states that radar detectors are banned in the United States. Radar detectors used in commercial vehicles are illegal.
Only if he has his radar gun on. Radar detectors are not cop detectors.
Radar detectors are legal. Radar scramblers however are NOT legal.
"Yes, it is legal to own and use a Cobra radar detectors in IL, but it is illegal to use in commercial vehicles, so do not be driving a semi truck with it."
The best radar detectors on the market are made by Beltronics. Beltronics is a leading manufacturer of the Vector, Professional, and Express radar and laser detectors.
Laser detectors detect laser beams used by law enforcement to measure speed, while radar detectors detect radio waves used by police radar guns. Laser detectors are more precise but have a shorter range compared to radar detectors. It's recommended to have both types of detectors for comprehensive coverage.
Yes, radar detectors are legal in Georgia, however there are laws about mounting objects on the windshield that may obstruct vision, so be careful in your method of mounting. anonymous@oola.com
From the Escort Radar Detectors site:Yes! Radar detectors are completely legal to use in non-commercial vehicles in 49 states. Only Virginia and Washington D.C. currently ban radar detector use in the United States. Radar detectors are illegal to use in commercial vehicles over 10,000 lbs. and in most Canadian provinces.
