Abstract

The need for refining the known methods of dispersion analysis of radio signal spectrum has been demonstrated. A new method was proposed on the basis of using the known peculiarities of the active spectrum of nonstationary processes. This method makes it possible to enhance the accuracy of spectral analysis and its informativeness about a brief malfunction of normal continuous operation of real physical entities, perform the synthesis of measured signals, and reduce the dispersion coefficient of the stationary dispersive delay line (DDL) about two times, while that of the tracking DDL about 15 times as compared with the DDL dispersion coefficient of the known methods.
