摘要

An adaptive modal MUSIC algorithm is constructed to localize an acoustic source by a vertical array operating under conditions of incomplete information on a waveguide propagation channel . The results of statistical modeling are presented, which demonstrate the probabilities of correct source localization versus the input signal-to-noise ratio and the sample size. The method is validated by its application to the experimental data observed in the Ladoga Lake. It is shown that this method ensures greater stability of the estimation procedure to mismatch between the true and expected signal replica compared to the conventional element-space MUSIC.
