The Dispersive Effect of a Medium Expressed as a Convolutional Filter,

Abstract

The dispersive filter function of the earth between two stations has been developed using the bandlimited spectra of the long period recordings. Different ways of applications are suggested. Experiments made with both Love and Rayleigh waves indicate that long period beamforming can be successfully performed provided the single sensor outputs are modified by filters correcting for the dispersion suffered within the array. Consequently a need for mapping the interiors of (large) arrays in terms of filters like the one mentioned, results. It is also suggested, without further experiments that the path effects between two epicenters can be studied along the same line. (Author)
