METHOD FOR DETECTING SOURCES OF RADIO RADIATIONS WITH LEAP-LIKE FREQUENCY ALTERNATION Russian patent published in 2006 - IPC G01S5/04 

FIELD: radio engineering, possible use in passive radio control systems for detecting and determining parameters of a set of transmitters with leap-like frequency alternation, simultaneously present in current receipt frequencies band.

SUBSTANCE: in accordance to method, additional signs are used for identification of signals with leap-like frequency autocorrelation function and selective functions of durations distribution and value of frequency leaps of elements of signal frequency-time matrix, preliminarily selected from input flow of signals with use of spatial mutual correlation connections between separate frequency-time signal components.

EFFECT: increased efficiency of detection of determining of parameters frequency-time matrix, describing rule of leap-like frequency alternation; average signal energy; most likely value of durations of separate radiations; speed of leap-like frequency alternation, azimuth and elevation of transmitter.
