Radar Bands

Most of the radars operate in UHF as well as microwave frequency bands. Now-a-days radars even use millimeter bands.

Following table-1 mentiona in general radar bands and peak power transmitted in each of these bands.

Following table-2 mentions all the Radar bands with their respective frequency range, wavelength and applications.

Radar Band	Frequency Range	Wavelength	Applications
HF	3 to 30 MHz	10 m to 100 m	Coastal radar systems, OTH radar
P	30 to 300 MHz	1m to 10m	applied retrospectively to early radar
UHF	300 to 1000MHz	0.3 to 1 m	very long range, ground penetrating radar
L	1 to 2 GHz	15 cm to 30 cm	Long range air traffic control and surveillance
S	2 to 4 GHz	7.5 cm to 15 cm	Terminal air traffic control, long range weather or marine radar
C	4 to 8 GHz	3.75 cm to 7.5 cm	satellite transponders, weather radar
X	8 to 12 GHz	2.5 cm to 3.75 cm	missile guidance, marine and weather radar, ground surveillance
Ku	12 to 18 GHz	1.67 cm to 2.5 cm	High resolution mapping, satellite altimetry
K	18 to 27 GHz	1.11 to 1.67 cm	Used by meteorologists to detect clouds, used by police to detect motorists with high speed.
Ka	27 to 40 GHz	0.75 cm to 1.11 cm	Mapping, short range, airport surveillance
mm	40 to 300 GHz	1 mm to 7.5 mm	This millimeter band is used for various radar applications
Q	40 to 60 GHz	5 mm to 7.5 mm	Used for military communications
V	50 to 75 GHz	4 mm to 6 mm	Very strongly absorbed by atmosphere
W	75 to 110 GHz	2.7 mm to 4 mm	76GHz LRR,79GHz SRR automotive radar, high resolution meteorological observation, imaging
