Abstract: During the past several years, the Radio Spectrum Measurement System (RSMS) of the National Telecommunications and Information Administration (NTIA) has measured the emission spectra and other characteristics of many radars operating in the government frequency bands. This report contains the emission spectra of 19 different types of radars, selected to show the different emission spectrum characteristics produced by a variety of radar output tube technologies. The radars include examples of ground-based search, airport surveillance, weather, and height-finding radars operating in L-band, S-band, or C-band.

Keywords: radar; emission spectrum; magnetron; radar measurements
