Abstract:

Silvers 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
