On a nonlinear inverse problems in electromagnetic sounding

چکیده
Electromagnetic induction measurements are often used for non-destructive investigation of certain soil properties, which are affected by the electromagnetic features of the subsurface layers. Knowing such parameters allows one to identify inhomogeneities in the ground, and to ascertain the presence and the spatial position of particular conductive substances, such as metals, liquid pollutants, or saline water. A linear and a nonlinear models are generally used to describe the interaction of an electromagnetic field with the soil, but if the conductivity of some subsurface layer is large only the nonlinear model is reliable.

In this paper we present di0erent inversion algorithms for nonlinear ill-posed problems arising in atmosphere remote sensing. The proposed methods are Landweber’s method (LwM), the iteratively regularized Gauss–Newton method, and the conventional and regularizing Levenberg–Marquardt method. In addition, some accelerated LwMs and a technique for smoothing the Levenberg–Marquardt solution are pro...
متن کاملAn Efficient Algorithm for Solving the InverseProblem of Locating the Interfaces Usingthe Frequency Sounding Data
We consider the inverse coefficient problem of locating the interface positions arising in frequency sounding of layered media. Such a problem is of particular interest in the exploration of geophysics, underwater acoustics and electromagnetics, optical sensing, and so forth. We found that a simplified algorithm can be constructed to determine the approximate positions of interfaces. Unlike the...

متن کاملApplication of different inverse methods for combination of vS and vGPR data to estimate porosity and water saturation
Inverse problem is one of the most important problems in geophysics as model parameters can be estimated from the measured data directly using inverse techniques. In this paper, applying different inverse methods on integration of S-wave and GPR velocities are investigated for estimation of porosity and water saturation. A combination of linear and nonlinear inverse problems are solved. Linear ...
