Analysis of Asymmetric Multipathing with a Generalization of the Double-Beam Method
Abstract An array method integrating source and receiver array beamforming is presented. The method is a generalization of previous work (Krtiger et al., 1993) to independent variation of slowness and azimuth in both the source and the receiver array. Compared to the analysis capabilities of a singl...
