Equation (2) can be used for acoustic wave fields or elastic wave fields with any degree of anisotropy. In the acoustic case, all elements in the discrete representation are just scalar values (pressure field). For the elastic case all scalars are replaced by three vectors. Using three vectors in R, means that we use three component receivers; if we also use three component receivers, we must use three vectors in S. Consequently, the elements in G are replaced by three-by-three block matrices. If we limit the number of components or employ wave type receivers or wave type sources, then mixtures of scalars and vectors appear in equation (2), but the analysis and the algorithm is still the same. The basic premise is still that we have a reciprocal acquisition geometry. Therefore this source equalization scheme is applicable to conventional single component data as well as multi-component data.
