Depends on the radar. Often C-Band is used (4-8GHz). This frequency is good since rain is quite reflective for it, and it doesn't attenuate as much as the higher X or K band frequencies.

Why is Doppler radar important?
Ship use radar for navigation and collision avoidance. The radar set on most board are equip with what is called the ARPA set which are a set of navigation aid that allow ranges baring and content baring to be examined. (when a constant bearing exist am risk of collision exists. Marine radar also allows the establishment of radar tracks to track boat, buoy and land masses. Some radar systems as also equipped transponder modes that work be transmitting on one frequency and listening on another, system such as this are used for Raycon Boys and search and rescue beacons. Marine radar fall into three classes S band 3GHz long range and low weather susceptible, X Band 9.375GHz closer range and can also see rain squalls etc and FMCW wideband radar witch is used for close range low power and port and marine navigation.
Which band of the electromagnetic spectrum has a frequency higher than x-rays?
Gamma rays
Which band of the electromagnetic spectrum has the lowest frequency?
That would be sound waves, or the audio spectrum.
What is an assembly of discrete frequencies spaced at regular intervals within a given frequency band?
It is called a COMB.
What is satellite orbital spacing?
orbital spacing is the satellite spacing between the satellites orbiting in same frequency band
What does Ka mean on a radar?
It is a carrier Frequency Band between 26.5GHz and 40GHz
What is the M?
The MSTAR is the Man-portable Surveillance and Target Acquisition Radar. It is an all-weather battlefield Doppler radar that operates in the J band.
What is the m-star?
The MSTAR is the Man-portable Surveillance and Target Acquisition Radar. It is an all-weather battlefield Doppler radar that operates in the J band.

Did the NZ cops change their radar frequencies recently so that radar detectors cant pick them up anymore?
Not really. For years they have been using K band and Ka band. Yet fairly recently they have mostly phased out the use of K band. New Zealand is allowed to use the same three Ka band frequencies which are used in the USA. These Ka frequencies are 33.8, 34.7 and 35.5. The 34.7 Ka frequency is the easiest to detect with any quality radar detector. The 35.5 frequency is poorly detected by some radar detector brands, notably Cobra. The 33.8 Ka frequency may be only fairly well detected by dome radar detector brands.
What wave is used in RADAR machines to clock the speed of cars?
RADAR = RAdio Detection And RangingRadio waves in the microwave band are used to measure the speed of cars using a technique called "Doppler RADAR", by measuring the change in frequency of the returned waves.These waves are electromagnetic waves.
What services are provided by Nexrad?
NEXRAD (Next Generation Radar), is a network of 159 S-band Doppler weather radars operated by the National Weather Service. It scans air movements and tracks active weather.
What do they mean by three band radar detectors?
A three band radar detector can read signals from 3 different band widths. This comes in handy with the new types of police equiptment out there.
What are the difference between 'X' Band radar and 'S' Band radar?
X-Band is 8 - 12 GHz, S_Band is 2 - 4 GHz.
What is a C-Band Doppler radar?
C-Band Doppler Radar is any Doppler radar system which operates in the C-Band of the electromagnetic spectrum (around 4.8Ghz). These are typically the radar systems seen at TV stations as they are affordable and powerful enough for their purposes.
What is the wave length of radar?
It depends on the frequency; The equation for wavelength is 300/frequency in megahertz. A radio emitting energy at 30MHz is producing waves 10 meters long.But since radars usually work up in the SHF and EHF spectra, the wavelengths are measured in centimeters or millimeters. An example: You are a cop who catches speeders with a K-band radar. It, like every other K-band radar, emits at 24.150GHz, or 24,150MHz. So...using that equation, you will find the wavelength is 1.2 centimeters.
