METHOD FOR RECOGNIZING FREQUENCY-MANIPULATED SIGNALS WITH UNKNOWN PARAMETERS Russian patent published in 2004 - IPC

Abstract RU 2236693 C1

FIELD: images recognition technologies.

SUBSTANCE: Method includes digitizing received signal in time and quantizing on level. On basis of combined use of methods of spectral and cluster analysis a problem of finding multicomponent radio signal and its components in analysis band is solved. Then frequency components are singled out and their contour lines are found. By means of calculating norm coefficient of mutual correlation of received contour lines of frequency components of multicomponent signals, and comparing it to threshold, determined during research, a decision is taken about relating received radio signal to class of signals with frequency manipulation.

EFFECT: higher possibility of correct recognition of frequency-manipulated signals under effect from noises and interferences and shorter process time for recognition due to use as main indication of value of norm coefficient of mutual correlation between contour lines of separate frequency components of signal.
