... on the precision of the tomographic model. Next, the advantages and disadvantages of single receiver in near surface model were analyzed based on the real data received from single receiver and array receiver simultaneously. Both the theoretical and practical data analysis results show that: relative to the array...

... precision. By applying our strategy to a 3D synthetic dataset, we show that the size of kernel matrices used in the Marchenko redatuming and Multi-Dimensional Deconvolution equations can be reduced by a factor of 34 and 6, respectively. We also introduce a TLR Matrix-Vector Multiplication (TLR-MVM...
