A Study of the Scanning Properties of Some Simple Reflections,
Abstract
A study has been made of the scanning properties of some singly-curved reflecting surfaces. First considered was the focal region field distribution when a plane wave is incident at various angles upon the reflecting surface. The information gained from this analysis was then used to study the scanning properties of the reflectors when sources are placed in the focal region. In particular, the parabolic cylinder was first analyzed, and it was found that this surface could be scanned only several beamwidths without severe coma lobes occurring in the radiation pattern. A modified surface was then studied and it was found that this surface could be scanned over plus or minus 10 beamwidths, simply by switching the location of the feed. (Author)
