Adaptive Algorithms for HF Antenna Arrays.

Abstract

The performance of an adaptive array system will not only be dependent upon the controlling algorithm, but also upon the specific environment in which the array is used. Isolating the contributions made solely by the control algorithm represents a formidable task, considering that adaptive array systems are inherently used in situations in which the interference environment is initially unknown, time-variant, or both. If an effective algorithm choice is to be made, it is important to be able to compare array performances in identical environments. The major focus of this study is to compare and contrast the performance of various control algorithms under identical conditions in a computer simulated adaptive HF antenna array system. After examining adaptive array systems and the role played by the controlling algorithms, this study concentrates on the selection and simulation of three specific algorithms. The simulation results are then presented in the form of a comparative evaluation of the selected control algorithms and relevant conclusions are drawn. Keywords include: HF Adaptive arrays, HF Channel simulation, HF Communications systems, and HF Adaptive algorithms.
