Dual frequency millimeter wave monopulse antenna

A novel, dual frequency, monopulse antenna system capable of simultaneous reception and location of signals at 34 pm2 GHz and 94 pm2 GHz using monopulse techniques has been developed. The state-of-the-art components necessary to implement this concept include a dichroic cassegrain subreflector, 34 and 94 GHz monopulse comparators, and low noise mixers. This paper traces the procedures and theory used in the development of the antenna system and presents experimental data.
