Abstract

A controlled ultrasonic laboratory experiment provides a detailed analysis of retrieving a band-limited estimate of the Green’s function between receivers in an elastic medium. In-steadof producing a formal derivation, this paper appeals toa series of intuitive operations, common to geophysical data processing, to understand the practicality of seismic interfer-ometry. Whereas the retrieval of the full Green’s function is based on the crosscorrelation of receivers in the presence of equipartitioned signal, an estimate of the impulse response is recovered successfully with 40 sources in a line covering six wavelengthsatthe surface.
