Gramian inversion

WebPrinciples of joint inversion using Gramian constraints Let us consider forward geophysical problems for multiple geophysical data sets. These problems can be described by the following operator relationships: () = (), =1,2,3,⋯, ; (1) where, in a general case, () is a nonlinear operator, WebThe joint inversion algorithm is presented in Section 2, including the design of the algorithm for use with the Gramian constraint in Section 2.1, a brief discussion on how the 2DFFT …
