Radio physics and radio astronomy| Summary: | Modification of the Fourier holography method for restoration of complex multifrequency reflection coefficient data of layered dielectric structure is proposed, concluding extrapolation of modulus square multifrequency reflection coefficient data at the first step of data processing. Extrapolation is carried out in an assumption that a source of the synthesized time domain signal, this latter to be minimized, is finite. Extrapolation procedure makes it easier to extract informative segment of reflectivity data, which corresponds to the structure, simplifying the choice of weighting function for extraction. Method of minimum of duration is used for solution of extrapolation problem. |
