Radar is just another pulsed electromagnetic wave, and may travel freely
throughout space. Radar transponders are left on our Moon and measure
orbital variations.
The upper frequency limit is only defined by our ability to operate technology at
high frequencies. Light radar (lidar) is commonly used on the highway, albeit in
Doppler mode.
There appears to be no practical limit to operational height.
-- The Doppler Weather Radar units operated by NOAA/NWS are routinely mounted
on towers at least 100-ft off the ground.
-- Air Route Surveillance Radar (ARSR) installations are routinely constructed on mountaintops.
-- All commercial airliners and military aircraft are equipped with Radar units, which
function quite satisfactorily while in flight.
-- Side Aperture Radar (SAR) has been used aboard the Space Shuttles and other artificial
Earth satellites to map the Earth's surface, with spectacular success.
-- Radar units have been used very successfully to map the surfaces of the moon
and several planets.

Radar can operate at frequencies as high as?
100000hz
How high can a large tornado lift objects?
Doppler radar has detected debris being carried as high as 20,000 feet by very large, violent tornadoes.
Why is weather radar important in detecting tornadoes?
Weather radar is an valuable tool in detecting tornadoes for many reasons. Tornadoes usually begin when two conflicting air masses collide, which radars detect as high and low fronts. Additionally, these weather systems may be detecting by radar based on their vortices and wind movement.
What does radar look like?
like a poke radar
What device tracks aircraft in the sky?
a radar
Radar can operate at frequencies as high as?
100000hz
Can you have a radar detector on a military base?
As of 2002, it is illegal to operate a radar detector on any U.S. military base.
What are the laws regarding use of radar detectors in Minnesota?
Minnesota Radar and Laser Jammer laws Radar laser detectors are legal to own and operate in passenger vehicles in the state of Minnesota. Currently the only state that it is illegal to operate a radar detector is Virginia and Washington D.C. Laser jammers are illegal to operate in the states of: Nebraska, Minnesota, Utah, California, Oklahoma, Virginia, Colorado and Washington DC. Radar jammers are illegal to own and/or operate in all 50 states per the Federal Communications Commission. Radar detectors are also illegal in commercial vehicles weighing over 10,000 pounds in all fifty states, per Title 49 Transportation Act. Radar detectors are also illegal to operate on any military base.
What is a radar mast?
A radar mast is a high platform to mount a radar antenna such as the radar has an unobstructed view.
What type of wave uses a radar?
Radars operate in the radio end of the em spectrum.
Are radar detectors legal in NY?
Radar laser detectors and laser jammers are legal to own and operate in passenger vehicles in the state of New York. Currently the only state that it is illegal to operate a radar detector is Virginia and Washington D.C.
Are radar Jammers legal in all 50 states?
Radar jammers are illegal to own and/or operate in all 50 states per the Federal Communications Commission.
What is the wavelengh of radars?
Basically there are no physical limitations of wavelength where a RADAR unit may operate, thereby it can operate practically on any wavelength from ELF (extremely low frequency) where wavelength can be as high as several hundreds kilometers or in Optical band like Laser RADAR (LADAR) who have wavelength of some microns . The limitations of RADAR operating wavelength is in their geometrical size of devices (transmitters, antennas and Receivers) required to produce such wavelength and their utilization . The following list is typical wavelength used by RADAR applications Search and Early Warning RADAR : >1- 10cm wavelength (HF- C band) Target Tracking RADAR : <10 cm Wavelength (C-band till milimmetric waveband) hope this helps
What is radar pedestal?
That is the tower or building that the radar sits on. Radar systems are usually placed in high places so they have an unobstructed view.
What is the advantage of radar over all other remote sensing technique?
Radar has the advantage of being able to penetrate through clouds, smoke, and dust, allowing it to gather data in all weather conditions. Additionally, radar can operate day and night, making it a versatile remote sensing technique for continuous monitoring. Radar can also provide high-resolution images and has the ability to detect small changes on the Earth's surface.
What frequencies do radar detectors use?
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.
What tells you how high a plane is flying?
An altimeter (altitude meter) tells the pilots how high the aircraft is flying. There are 2 types of altimeters commonly used in aircraft: pressure altimeters and radar altimeters.
