Analysis of monopulse crossfeed performances in presence of rough sea multipath

Monopulse radars are widely used in tracking systems, due to their relative simplicity and precision. The presence of, possibly rough, sea scattering impairs the tracking capabilities of these radars. A special monopulse setup, the crossfeed, has been proposed in the past to provide an automatic cancellation from smooth sea multipath. In this contribution the performances of such a system are analyzed in presence of rough sea scattering, with particular attention to performance degradations due to possible phase errors in the passive network implementing the comparator.
