Optimization of the shape of Gaussian beams [PDF]
SEG Technical Program Expanded Abstracts 2001, 2001 The applicability and accuracy of the Gaussian beam method depend on the proper choice of the shape of beams. Gaussian beams become inaccurate solutions of the elastodynamic equation if the velocity field changes considerably within the beam width. We present a procedure of determining the optimum initial shape of Gaussian beams based on minimizing the
