AbstractThe dual polarized high-power synthetic conical scan tracking system was designed for operation over the frequency range from 1700 to 2400 mc. This feed was developed for an existing 33' parabolic reflector which is presently located at the Floyd Test Site in Rome, New York. The feed network is located at the focal point of a parabolic dish and is fabricated in WR-430 waveguide. The system provides a horizontally polarized on-axis beam for transmission. It also provides two conically scanning receiving beams at a frequency different from the transmit frequency. One of the receiving beams is vertically polarized; the other is designed to receive the orthogonal horizontal polarization. The conical scan is synthetically generated and individual channel control is provided to allow the two receiving beams to be aligned. The feed system may be converted to provide monopulse outputs by simply removing the synthetic conical scanning mechanism.
