Abstract:

This report is concerned with a study of the sidelobe performance of a broad range of antenna types. The survey is based almost entirely upon data available in the open literature, although in reviewing this material, the authors have tempered the information in the light of their own experience, and that of their colleagues, in this field. The emphasis of the review has been directed toward establishing the level of sidelobe suppression which can be achieved with antennas of differing types and dimensions and towards determining to what extent these levels represent fundamental limitations with respect to sidelobe performance. Efforts have also been made to identify the principal parameters governing the sidelobe performance for any given antenna type. The main conclusion of this survey and review is that sidelobe suppression to lower levels than that commonly achieved with existing antennas is, in many cases, both theoretically and practically feasible. The rather indifferent sidelobe performance of many existing antennas is considered to be a result of insufficient emphasis being given to this aspect of the system electrical performance. This has often led to an acceptance of levels of sidelobe radiation which, in view of the existing jamming threat, must now be considered as totally unrealistic.
