Synthesis of Resistive Tapers to ontrol Scattering Patterns of Strips.
Abstract
This document outlines a technique for synthesizing a resistive taper that generates desired bistatic scattering and backscattering patterns from a strip. Antenna synthesis techniques relate the scattered field to the induced surface current density to get low sidelobes and nulls in the scattering patterns. Either physical optics or an integral equation approach relates the surface current density to the resistive taper. Numerical methods are used to analyze the errors in measuring a resistive taper on a sheet with the four point probe. The impact of the manufacturing and resistivity measurement errors on the low sidelobe scattering patterns is examined. Finally, experimental bistatic scattering patterns of a tapered resistive sheet and a metal plate are compared with theoretical predictions.
