AbstractThis paper looks at the fundamental qualities of large reflector antennas that make them vulnerable to interference, and reviews the recent trends toward passively and actively placing deep nulls in the direction of unwanted signals. The basic limitations of adoptively controlling the sidelobes of large reflector antennas are presented. The effectiveness of cancelling sidelobes without disturbing the main beam is described and verified with measurements taken during experiments at Harris’ facility.
