- Abstract
The work described herein discusses the application of a high-resolution frequency wavenumber method-the Multiple Signal Classification (MUSIC) method which is different from the traditional frequency wavenumber (F-K) method for detecting and estimating the direction of travel (DOT) of infrasound. Synthetic infrasound signals were superposed on top of white noise to assess the performance of the two algorithms with respect to signal-to-noise ratio. The synthetic array is composed of four elements that are aligned and equally spaced on a line. Preliminary results demonstrate the MUSIC method can lead to more accurate DOT detection than the F-K method.
