| | Abstract | | The image domain seismic interferometry is a direct migration method for passive seismic data. This method is implemented by combining the reverse time migration with the concept of seismic interferometry, the summation of the crosscorrelation of forward and backward extrapolated wavefields. In this study, I focus on the sensitivity kernel calculated with the seismic records from two receiver points. It is important to analyze the sensitivity kernel obtained under different conditions of the observation and the migration velocity. The velocity model for the image domain interferometry makes effects on the migration result and on the phase stationarity of the interferometric image accumulation. The quantitative analysis of the sensitivity kernel has potential to estimate velocity distribution. |
