Modification of Newton-Kantorovich iteration procedure for piecewise-constant real permittivity profile reconstruction

General Newton-Kantorovich method and its new modification for piecewise-constant real permittivity profile reconstruction on the basis of multifrequency reflectometry data are described. The method of spectral analysis based on the chain-fraction approximation is proposed to be used as stage of mod...

Beschreibung
Zusammenfassung:General Newton-Kantorovich method and its new modification for piecewise-constant real permittivity profile reconstruction on the basis of multifrequency reflectometry data are described. The method of spectral analysis based on the chain-fraction approximation is proposed to be used as stage of modified Newton-Kantorovich method and is also described. Some results of numerical simulation are presented.
