ABSTRACT:
An improved dome antenna system wherein compensation for cross polarized signal components in a received difference pattern of the feed array of the system is accomplished with a second array cross polarized to the feed array. This second array is density tapered to establish an aperture distribution function that is substantially equal to the aperture distribution function of the feed array. Weighting factors, programmed as a function of the boresight scan angle, are applied to the output signals of this second array and the weighted signals are subtracted from the difference signals of the feed array.
