摘要：

A new technique for calculating interstation Green's functions and attenuation coefficients for seismic surface waves is presented. The interstation Green's function is evaluated from the autocorrelation functions of the seismograms, which are obtained from a maximum entropy process. Since a data-invariant time window is not used, the evaluated Green's functions gives reliable information on both the amplitude and the phase spectra of the system. This new technique is compared with other methods by applying them to both synthetic and real data from a path in the Canadian shield. © 1990 Birkhäuser Verlag.
