Abstract

A Fourier transform method developed for the quiet-zone field analysis of serrated compact range reflectors is presented. The analysis relies upon a variable spectrum sampling rate which increases with the separation between the reflector aperture and the quiet-zone plane. Errors caused by rim approximation inherent in techniques involving numerical integration are avoided by employing a closed-form expression for the plane wave spectrum of a uniformly illuminated aperture which is bounded by a polygon. The method has been validated for the case of uniform illumination by computing the quiet-zone fields of several apertures, and its utility was demonstrated for several reflectors which are representative of commercial compact range designs.<>
