Abstract :
Outlines an eigen-structure algorithm for passive seismic array data. The approach combines broadband multicomponent and narrowband multi-sensor eigen-structure routines. Synthetic data is used to demonstrate the algorithm´s ability to resolve multiple signals in both bearing and wavenumber. Analysis of three-component seismic array data is also shown
