There is no standard definition of Ka-band. IEEE Standard letter designations for Radar Bands define the nominal frequency range for Ka band in the range 27–40 gigahertz (GHz) in Tables 1 and 2 of IEEE Standard 521 [2] i.e. wavelengths from slightly over one centimeter down to 7.5 millimeters. [3]
K-band (18–27 GHz): due to the 22 GHz water vapor absorption line, this band has high atmospheric attenuation and is only useful for short-range applications. Ka-band (K-above band, 26.5–40 GHz): mainly used for satellite communications, radar and experimental communications.
Ka band is the latest and quickly becoming the most common radar band, typically found at 33.8, 34.7, and 35.5 GHz. In recent years, law enforcement has favored Ka-band because it is the most ...
A radar detector is an electronic device used by motorists to detect if their speed is being monitored by police or law ... K-Band 24.125 GHz, Ka-Band 34.36 GHz ...
In the U.S., law enforcement typically uses one of three radar and laser types–the X, K, and Ka bands. X band is the oldest form of radar used by law enforcement and is now uncommon. Its ...
Demonstrate low-cost Ka band radar technology, with a vertical resolution of 250m and a horizontal resolution of at least 10 km. Its radar sensitivity should also be better than 20dBZ. Use Ka-band radar from a 6U CubeSat; Profiling precipitation falling on Earth
Because SWOT operates at Ka-band's relatively short wavelengths, 11–7 mm (27–43 GHz) – compared to the Ku-band Jason series, 25–17 mm (12–18 GHz) – and at near-nadir incidence angles (<5°), it is designed to be uniquely appropriate for measuring water surface elevations and inundation extents.

Since the late 2000s, a meteorological 35.5 GHz Ka-band commercial cloud radar designed by METEK GmbH in collaboration with the Institute for Radio Astronomy, Kharkov (Ukraine) is in the market. Nowadays, there are eleven systems monitoring the cloud properties continuously in different sites, most of them in Europe.
