The resolution function in linearized born and Kirchhoff inversion,d-aperture and band limited signals, the output from a general inversion scheme will be a distorted or blurred image. If the transmitter/receiver layout, the signal bandwidth and the (initial) background model are all known, this distortion can be computed employing the concept of resolution functio

Optimization tools for Tikhonov regularization of nonlinear equations using the L-curve and its duaov problem with an unknown regularization parameter. The nonlinear L-curve is the size of the solution considered as a function of the size of the residual (when the regularization parameter is changed). The dual curve connected to the nonlinear L-curve is defined as the value of the minimization fu

The PP-TSVD algorithm for image restoration problems, solutions without any a priori information about the locations of the break points. Here we describe an extension of this algorithm designed for two-dimensional inverse problems based on a Kronecker-product formulation. We illustrate its use in connection with deblurring of digital images with shar

Smooth versus sharp Frechet kernels in time-distance helioseismology,that are constant along the ray path and zero elsewhere. Finite-wavelength effects imply that actual Fréchet kernels are smoother than the implicit deltaness of the ray kernels. One way to account for the finite-wavelength effects is to make use of Fréchet kernels based on the first Fresnel zone (Sn

Covariance modelling for merging of multi-sensor ocean surface data,ric estimates by merging different types of surface data is explored. The focus in this paper is on the modelling of covariance functions of sea surface height and sea surface temperature and identification of the appropriate spatial and temporal correlation scales. It is shown that on the mesoscale

Inversion of 2D geoelectrical data by iterated multichannel deconvolution,inversion procedure are useful. This paper presents a 2D inversion procedure that uses the 2D Fréchet derivative of the homogeneous halfspace as approximate partial derivatives. The inversion at each iteration step is carried out as a multichannel deconvolution that solves the inverse problem in the
