Abstract
A dually polarized monopulse feed system for processing radar signal information from a target so the target may be identified and tracked includes a symmetrical multimode input waveguide, a coupler for separating polarized modes of signal waves to identify and track the target, waveguides for rejecting and terminating selected polarized modes of signal waves, and a backshort for reflecting selected polarized modes of signal waves.
Claims12
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.
