The Federal Communications Commission (FCC) regulates frequency use by setting specifications for transmit frequency, power, bandwidth, modulation, and location, to name a few, and requires a license for many uses. The FCC does NOT cover the CALIBRATION of radar units, radar ACCURACY, or OPERATOR capability requirements.

Military Radar Bands

 

Military radar band nomenclature (L, S, C, X, Ku, K and Ka bands) originated during World War II as a secret code so scientists and engineers could talk about frequencies without divulging them. After the war the codes were declassified, millimeter (mm) was added, and the designations were eventually adopted by the IEEE -- Institute of Electric and Electronic Engineers. Military radar band nomenclature is widely used today in radar, satellite and terrestrial communications, and electronic countermeasure applications, both military and commercial.
