A Comparison of Two Frequency Domain Adaptive Beamforming Algorithms for Sonar Signal Processing.

Abstract

Computer simulation studies of two frequency domain adaptive beamforming algorithms are presented. The two algorithms are the frequency domain adaptive beamforming modified least-mean-square algorithm, and the proposed new frequency domain adaptive beamforming algorithm based on modified adaptive linear prediction-error filtering. The simulation studies were conducted to determine the multiple broadband target localization capability and the full angular coverage capability of the two algorithms. The number of iterations that the adaptive algorithms took to reach a minimum estimation error was determined. The algorithms were evaluated at several signal-to-noise ratios. Finally, using the results of the simulation studies a comparison between the two algorithms is performed.
