In this paper we develop a technique for detecting and retrieving the common harmonics in a multi-channel setup. The different (complex) signals are arranged in a set of Hankel matrices. First, we compute the singular value decomposition (SVD) of these matrices in order to denoise and normalize the relevant subspaces. Then a second SVD is applied to detect and select the common subspace. The poles...
This paper deals with the detection of polarized seismic waves, the estimation of their polarization parameters, and the use of these parameters to apply waves separation. The data, containing several polarized waves together with some noise, are recorded by two-component sensors. After a review presenting the tools classically used to estimate the polarization parameters of a wave in the time domain...
