Beamforming Method Based on Least Squares Algorithm and its Distributed Computing Approach

Abstract:

Beamforming performance of autonomous, distributed sonar array degrades due to random position deviation. A new algorithm for beamforming based on Least Squares (LS) approximation of the desired beampattern is proposed in this paper. Elements of autonomous, distributed array are battery-powered and capable of computing with microprocessor. Centralized approach has shortcoming of failures due to excessive power consumption and lower fault-tolerant capability. Distributed computing approach of LS solution has profound significance with respect to longer life period and better robustness for autonomous sonar array systems.
