Microwave Fourier-holography approach improvement via minimum duration amplitude multifrequency data extrapolation

The problem of restoration improvement of complex multifrequency reflection coefficient data of layered dielectric structure from scalar amplitude data measurements is considered. It is proposed to use extrapolated amplitude multifrequency data in the framework of developed Fourier-holography approach, making it easier to extract informative segment of data, which corresponds to structure, in the time domain. Extrapolation is carried through special nonquadratic regularization procedure based on method of minimum of duration. Results of numerical simulations and experimental data processing are given.
