Complex reflection coefficient determination via digital spectral analysis of multiprobe reflectometer output signals

摘要

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 complex reflection coefficient estimation is analyzed.
