Abstract

A new tomography method of spectrum analysis is suggested in the article, which connects an analog filtration with the original digital processing. A number of advantages of the method are a result of such connection. Compared with the methods based on a digital processing of periodogram or an autocorrelation function of the analyzed signals which are suitable only for low-friquency signals, the suggested method is free from such restriction about frequency range and can be applied both for low-frequensy and for high-frequency signals. And thus the tomography method is capable to provide high precision of spectrum analysis comparable with the digital methods precision and far surpassing the possibilities of the analysis spesifically by means of a comb of resonators.
The tomography method allows to reach new qualitative result ( to restore complex spectrum by means of power measurements of the signals at the outputs of the comb of resonators. Complex spectrum allows to restore a signal, that is why its definition is quite an actual problem. Tomography method allows to solve this problem with the help of simple power measurements. In the article, there is given the mathematical description of the method as well as the scheme of its realization which was also elaborated by the author.
