SUMMARY:

We propose an efficient methodology for the complete version of the wave oriented to atarget area through
the Patched Green’s Function-(PGF) method. The method consists of separating the velocity model into
two regions of interest, “external” and “target” regions. When trying the verylarge system it can be
considered as projected arrays. In addition, we address a situation in whichthe observed data is
contaminated with noise. In this scenario, we formulate a FWI rubased on themaximization of the
Reney statistic together with the PGF method, we build a robust objective function in this scenario scenario.
Results relevant to the results obtained with the results-based version of the FWI, based on the results
obtained with the PGF methodology, related to the results obtained with the results-based method of the
FWI based on the results statistics based on the FWI, especially not -Gaussians. The main advantage of the
PGF method is that it is able to optimize the approximate methods of thecontinuous method in each ideal
method, it is worth emphasizing that mathematically the PGF methodis mathematically exact and does not
involve the PGF method is thus a computationally approximated cost to precision, robust of the FWI based
in the Reney statistic to data with non-Gaussian noise, it maybe related to the entropic index, especially for
the value ofα→2/3.
