文摘

We propose a Super-Gaussianity based Receiver Deghosting (SRD) method in the t-x domain. The SRD is flexible for various source/receiver configurations. The SRD obtains reliable estimations of the ghost parameters automatically. The SRD introduces an adaptive predefined discrete solution space for 2D grid search method. The SRD adopts a 2D average filter to improve the estimations of the ghost parameters.
