METHOD OF ULTRA BROADBAND SIGNAL DETECTING Russian patent published in 2017 - IPC G01S7/28 

FIELD: electricity; radio engineering.

SUBSTANCE: invention relates to means for electronic equipment radio monitoring and can be used for detecting illegally installed radio-electronic devices using pulsed ultra-broadband signals. In the method of broadband signal detecting ultra-wideband signal is supplied into plurality of m parallel connected band-pass filters with mutually adjoining band passes of the same value, wherein of band pass width of band-pass filters is much less than signal spectrum width. i pairs of band-pass filters are randomly selected, signals from the outputs of each of which are transferred to intermediate frequency, amplitude detected and digitized and quantized by level, converting them to digital form, after which correlation coefficient between received digital signals for each pair of band-pass filters is calculated. Correlation coefficient calculated value is compared with threshold value with correlation coefficient exceeding threshold value, decision is made on signal presence, correlation coefficient calculated values are recorded into cells, each of which corresponds to numbers of band-pass filters, symmetrical matrix, in which number of columns and rows is equal to number of m band-pass filters, derived values are compared, cell with maximum value of correlation coefficient is determined and main signal frequency is determined.

EFFECT: technical result consists in detection of radio electronic devices using ultra-broadband signals in predetermined frequency band, under conditions of signals parameters uncertainty, as well as determination of main frequency of detected radio electronic frequencies.
