基于小波的面波层析成像--测量与反演
Measurements of group and phase velocities of surface waves are often carried out by applying a series of narrow-bandpass filters centered at specific frequencies to wave packets and estimating the arrival times at the peak envelopes and phases of the Fourier spectra.The conventional approach,however,may not fully account for the inherently nonstationary char-acteristic of seismic signals.We present a wavelet-approach to retrieve inter-station dispersion and dissipation properties from surface waves.
