1. A dually polarized monopulse feed system for processing radar signal information from a target so the target may be identified and tracked, the system comprising:

  • a symmetrical multimode input waveguide;

    a coupler to process vertical modes of signal wave polarizations;

    a monopulse comparator to process horizontal modes of signal wave polarizations;

    means for rejecting and terminating selected modes of signal wave polarizations; and

    a back short for reflecting selected modes of signal wave polarizations.
