Low Sidelobe Scanning Beams for Parabolic Reflectors,
Abstract
In this paper, it will be shown that low sidelobe scanning beams for parabolic reflectors can be achieved by using feed array with tandomly arranged orthogonal matrices. The matrix immediately behind the feed array transforms the focal field to match the aperture plane distribution including both amplitude and phase distortions induced by the feed array when located off-axis. With proper amplitude taper and phase compensation, low sidelobe scanning beams can then be realized. Feed array configurations, orthogonal matrices and secondary far field patterns will be presented in detail.
