Application of GCV in Geophysical Diffraction Tomography

P032 Application of GCV in Geophysical Diffraction Tomography E. Santos (CEFET/BA and Stanford University) & A. Bassrei* (Federal University of Bahia) SUMMARY Since inverse problems are usually ill-posed it is necessary to use some method to reduce their deficiencies. The method that we choose is the regularization by derivative matrices. When a first derivative matrix is used the order is called the first. Then second order regularization is when the matrix is formed by second order differences and order zero means that the regularization matrix is the identity. There is an important issue in regularization which is the selection of
