Rayleigh-Wave Multipath Analysis Using a Complex Cepstrum Technique

Abstract

Homomorphic deconvolution is applied to separating the components of a convolution in which multipath Rayleigh-wave propagation is modeled as the convolution of a signal S with a multipath operator m. The technique is applied to a number of synthetic waveforms with fairly simple multisource and/or multipath Rayleigh-wave characteristics to demonstrate the separation obtainable between S and m. The technique is also applied to several events recorded at LASA and ALPA, and results of the method as applied to actual Rayleigh-wave recordings are presented.
