Abstract :
The 2-D elementspace and beamspace extensions of Friedlander´s (1993) wideband interpolated root-MUSIC technique are applied to azimuth-velocity source location using real seismic data from the GERESS array (Germany). We demonstrate that the 2-D interpolated root-MUSIC is able to estimate the parameters of a typical seismic source with a good accuracy. The use of the interpolated root-MUSIC and its beamspace modification is motivated by the significant reduction of processing time allowing on-line implementation
