Named X band because the frequency was a secret during WW2. Diffraction off raindrops during heavy rain limits the range in the detection role and makes this suitable only for short-range roles or those that deliberately detect rain. K u: 12–18 GHz: 1.67–2.5 cm: High-resolution, also used for satellite transponders, frequency under K band ...
Frequency bands in the microwave range are designated by letters. This convention began around World War II with military designations for frequencies used in radar, which was the first application of microwaves. There are several incompatible naming systems for microwave bands, and even within a given system the exact frequency range ...
AN/APS-1 X band radar tail warning radar; AN/APS-2 S band search radar used with AN/APQ-5 for North American PBJ-1 PBM-5S Consolidated PB4Y-2 Privateer; AN/APS-3 X band search and bombing radar for PBJ-1 Consolidated PBY-6A Catalina Grumman TBM-1D/3E Lockheed PV-1 Ventura Lockheed PV-2 Harpoon and North American P-82F Twin Mustang
The antenna uses phase-frequency electronic scanning technology, forming sharp 3D pencil beams covering large surveillance and track volume. It uses a rotating platform with a high scan rate (30 RPM) to provide 360 degree coverage. The radar is designed with high resistance to electronic countermeasures (ECM) and anti-radiation missiles (ARM). [1]
Marine radars are used by ships for collision avoidance and navigation purposes. The frequency band of radar used on most ships is X band (9 GHz/3 cm), but S band (3 GHz/10 cm) radar is also installed on most oceangoing ships to provide better detection of ships in rough sea and heavy rain condition.
TPY-2 radar in travelling configuration View from the back on a deployed TPY-2 radar. The AN/TPY-2 Surveillance Transportable Radar, also called the Forward Based X-Band Transportable (FBX-T) is a long-range, very high-altitude active digital antenna array [1] [2] X band surveillance radar designed to add a tier to existing missile and air defence systems.
X band is used in radar applications, including continuous-wave, pulsed, single-polarization, dual-polarization, synthetic aperture radar, and phased arrays. X-band radar frequency sub-bands are used in civil, military, and government institutions for weather monitoring, air traffic control, maritime vessel traffic control, defense tracking ...
It sits above the U.S. IEEE-designated V band (40–75 GHz) in frequency, and overlaps the NATO designated M band (60–100 GHz). The W band is used for satellite communications, millimeter-wave radar research, military radar targeting and tracking applications, and some non-military applications.
