  • 摘要:The method for isolating the clock frequency of direct digital synthesizers, as well as algorithms and devices for isolating and automatically compensating phase distortions, that significantly improve the spectral characteristics of the formers of the probing signals of georadars used for geodynamic monitoring are considered in the article. The method is substantiated, explanatory oscillograms, spectrograms, and the results of the experimental researches, confirming the authenticity, are presented.
