Abstract : This report summarizes the progress and results of the first of a three-year study whose goal is the use of fault tolerant distributed and parallel processing techniques to decrease the cost and improve the performance and reliability of large, disposable sonar arrays. In this first phase, tasks have concentrated on the study, design, and analysis of the fundamental components in the design and analysis of parallel and distributed computing architectures and algorithms for fault tolerant sonar arrays as well as models for their baseline counterparts. An interactive investigation of the interdependent areas of topology, architecture, protocol, and algorithms has been conducted. The results of this first phase have helped to identify the optimum candidate network topology, architecture, hardware components, and interface protocols for the system architecture and a set of fundamental decomposition techniques and parallel algorithms for a representative set of time domain and frequency domain beamforming methods.
