Military Radar Bands. Military radar band nomenclature, L, S, C, X, Ku, and K 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 and Ka band and millimeter (mm) were added. Military radar band nomenclature is widely used
