Implementation of adaptive arrays in the Block Oriented Systems Simulator

The authors 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., (1975) 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. Testing the algorithms with simple inputs and checking the algorithms ability to track these inputs was the second step. The last step was to test the algorithms with the arrays
