Abstract

We apply two-dimensional (2-D) elementspace and beamspace extensions of Friedlander's (Friedlander 1993; Friedlander and Weiss 1993) wideband interpolated root-MUSIC technique to azimuth-velocity source location using measured seismic data from the GERESS array. Real data processing shows that 2-D interpolated root-MUSIC is able to estimate the parameters of a typical seismic source with good accuracy. The use of interpolated root-MUSIC and dimension reduction via beamspace is motivated by a dramatic reduction of processing time, allowing efficient on-line implementation
