Large-Array Signal and Noise Analysis, Extraction of Long-Period Rayleigh Waves from Ambient Noise

Abstract

This report presents the results of an investigation of processing techniques for extracting long-period Rayleigh waves from ambient noise by using various geometries of the LASA long-period vertical array. Delay-and-sum and multichannel signal extraction are the processing schemes evaluated.
