The possibility of complex reflection coefficient value estimation via discrete Fourier transform of output signals of equidistant probes in multiprobe measuring line is considered. This approach provides linear problem and explanation of known previous results. The general features of this approach and the holography with colliding beams are under discussion. The influence of noise on accuracy of...
Localization of plane wave decomposition for the analysis of transverse-inhomogeneous structures has been considered. The algorithm of numerical implementation of local plane wave decomposition on the basis of parametric spectral analysis is offered. Its advantage over algorithm based on the discrete Fourier transform has been shown for the analysis of reflection from the secondary aperture.
