Abstract : The C-band transmitter is one of the four radar transmitters which are included in the Four-Frequency Radar System. The Four-Frequency Radar in its entirety is an airborne system capable of measuring target characteristics and terrain backscatter, and has been used in the synthetic aperture mode to map sea ice, waterborne oil pollution, and land and sea surfaces. The four radar transmitters operate at P/UHF (428 MHz), L band (1228 MHz), C band (4455 MHz), and X band (8910 MHz). Previous attempts to produce the required power and versatility at C band netted only partial success, and in due course, it was decided to replace and update the C-band transmitter. A new transmitter has been produced by NRL and installed as a part of the airborne Four-Frequency Radar System. The new transmitter uses an electrostatic focused Klystron and meets its design goals while having approximately one-half the weight and cubic displacement of the older transmitter. The Four-Frequency Radar is a valuable research tool and the addition of a stable dependable transmitter in the C-band region gives it the balance and continuity envisioned in its inception. (Author)
