PROCESSING OF PACKAGED RADAR PROBING FM SIGNALS FOR RETRANSLATION SYSTEMS IN TECHNICAL DIAGNOSTIC

A.F. Velichko, S.A. Velychko
Annotations languages:

The relationships for the spectral components of FM signals of the diagnostics retranslation systems are obtained. Analysis of basic properties of odd and even harmonics in the spectrum of the received signal are produced. The relationships for the spectral component of the reference signal are received, the parameters of which are necessary for digital processing. The method of formation of oscillations, which are intended to exclude phase additions, caused by auxiliary fluctuations is determined. When the signal has fixed characteristics of one of the components of the packet, the main sources of filling the digital arrays of data signals at the time intervals are determined.
