Method of processing seismic data for the decomposition of a field of the wave in harmonic components and applications for the determination of the collections angular reflectivity

摘要

Method of processing seismic data representative of at least one field, characterized in that it determines the harmonic components of the field of local wave at a point p is given in the - ground using an iterative process according to which a harmonic of order n + 1, n being a positive integer, is determined as a function of one or more harmonics of order n or less than that which is applied at least one filtering, which depends on at least one parameter local to the point p, this parameter premises being chosen from among the components of the wave vector, the frequency of the field of the local speed, the parameters of premises or any combination of these various parameters.
