Passive spatio-temporal inverse filter

, 2012
Green's functions recovering from ambient noise require strong hypothesis, including isotropic distribution of the noise sources. This ideal distribution is not achieved in most of the experimental applications, yielding to bias in the Green's function reconstruction. To minimize this bias, a spatio-temporal inverse filter is proposed.
