Tolerance manufacturing effects in crossfeed monopulse radars in presence of rough sea scattering

In this paper the performances of a crossfeed system was analyzed in presence of stochastic rough sea scattering, whereas in other literature the crossfeeds monopulse have been analyzed only under the hypothesis of flat earth and perfectly smooth sea (Schenkel, 1987). Furthermore the effect of manufacturing tolerances in the passive network backing the antenna was considered. These errors can lead to small phase bias in the different monopulse channels, leading to inaccurate tracking. The different effects of these phase errors on standard and crossfeed monopulse radars were discussed.
