Effect of Fresnel Zone Blockage on Very Low Sidelobe Antennas,

Abstract

Silver's method for estimating antenna sidelobes owing to blockage is accurate only for obstacles in the near field; it is unduly pessimistic for obstacles elsewhere in the Fresnel zone. A method for calculating the sidelobe level in the latter case is presented and applied to some problems that are typical as well as practical. (Author)
