An example of seismic time picking by third-order bicoherence

摘要

Comventional seismic time-delay estimation relies on the crosscorrelation that quantifies the similarities between two measurements in the second-order time domain. When the noise correlation in the measurements is considerable, the cor- relation peak can be substantially distorted, resulting in im- precise and even biased estimation of the time delay. The syn- thetic data computed by Ikelle et al.
