Broadband Signal Enhancement of Seismic Array Data: Application to Long-period Surface Waves and High-frequency Wavefields

Abstract

The objectives of this program of broadband signal enhancement of seismic array data were the: (a) Development of new techniques for enhancement of low signal-to-noise surface wave signals recorded by broadband seismic arrays. The tasks were: Assembly of test data sets; Estimation of dispersion curves for reference events; Algorithm development. (b) Research on fundamental properties of high-frequency wavefields. The tasks were: Analysis of array data using scientific visualization tools; Analysis of signal coherence versus receiver separation and frequency for different array data; Analysis of frequency dependent polarization for different array data.
