MODELING AND MEASUREMENT TECHNIQUES FOR LARGE SPHERICAL ARRAYS.

Abstract

This is the final technical report on Modeling and Measurement Techniques for Large Spherical Arrays. The objective of the program was to develop a reliable economical method for the verification of the design concepts and analytical predictions of the radiation performance of large spherical arrays prior to full-sized antenna fabrication. The objective was to be accomplished through a program of analyses and experimentation which accomplished the following: (1) Establishment, through test and evaluation, of the array element simulator. (2) Detailed design of a spherical model having an aperture of 100 lambda. (3) Establishment of a simple feed system for the spherical model array. (4) Verification of the modeling techniques through experimentation with the spherical model containing a small number of element simulators. A frequency scaled linear array of 145 elements simulators located uniformly along a 120 degree arc of a great circle on a spherical surface was constructed and evaluated.
