Spherical Near-Field Scanning: Experimental and Theoretical Studies

Abstract

This report documents the evaluation of spherical near-field scanning algorithms and computer code developed at the National Institute of Standards and Technology. The experimental work is primarily a comparison of probe- compensated spherical and planar near-field measurement results for a common test antenna. Theoretical work is largely supportive of the experimental effort, but some peripheral topics are developed. For example, (1) application of spherical near-field measurements to the determination of incident fields in compact ranges; and (2) spherical-wave expansions for the fields of a uniformly excited aperture (to facilitate the creation of the analytic test data).
