Implementation of Adaptive Arrays in the Block Oriented Systems Simulator

Abstract

The Information Transmission Branch of the Wright Research and Development Center wants to have a tool to evaluate contractor's proposals concerning adaptive arrays. This tool could be the traditional component level simulation which is difficult to modify and is generally applicable to only one array configuration. This study investigated the feasibility of implementing adaptive array algorithms in a simulation program called the Block Oriented Systems Simulator (BOSS). Two algorithms in particular were used: the least mean square (LMS) algorithm in real and complex form originally developed by Widrow, et. al. and the Applebaum algorithm. Two arrays were simulated with simple isotropic radiators used as the array elements. The first array used two elements spaced one half wavelength apart. The second array used four elements with variable geometry. The approach taken was to first implement the algorithms and arrays in the simulation language. (jes)
