Resolving diversely polarized, superimposed signals in three‐component seismic array data
GEOPHYSICAL RESEARCH LETTERS(1996)
摘要
I present a novel processing approach for three-component seismic array data that entails a succession of principal component analysis, factor analysis, and principal component analysis. This formulation represents an effort to conduct principal-component polarization analysis on isolated signals whose propagation direction and apparent propagation direction have been estimated a priori using high-resolution wave front analysis. A comparison of the signal parameter estimates realized using single-site three-component, vertical-component array, and three-component array data is provided.
