Analysis and Synthesis of Spatial Filters that Have Chebyshev Characteristics

Abstract

Stratified dielectric filters in the spatial domain are being synthesized by a new Chebyshev technique recently developed at AFCRL. Used as radomes at the face of an array, these filters can control the residual grating lobes that plague limited sector-scanning and multiple-beam arrays in airport precision-approach radar (PAR) systems and synchronous satellite communications antennas. Formulas and charts are given for designing two-, three-, and four- layer filters. The characteristics of several four-layer filters are compared and discussed.
