摘要
The research on the resolution of seismic tomography can not only help us understand the ability of inversion, but also give instructions on setting of tomography parameters and optimization of seismic survey. We compare two previous methods calculating the seismic resolution of Fresnel volume tomography (FVT), and propose the corresponding optimization method. Through quantitative experiments on the synthetic data, some regularities about seismic resolution of FVT are summarized. Also, the resolutions of raypath tomography and FVT are compared. Finally, we give suggestions on seismic survey design and tomography, especially on parameters setting, including model partition and variable window size for smoothing in dynamic tomography.
