METHOD OF DETECTING UNAUTHORIZED INSTALLED ELECTRONIC DEVICES USING FOR INFORMATIONAL TRANSMISSION BROADBAND SIGNALS Russian patent published in 2018 - IPC G06F21/88 G01S3/02 

FIELD: radio monitoring.

SUBSTANCE: invention relates to radio monitoring equipment of electronic equipment, namely to the detection of unauthorized radioelectronic devices using broadband signals. Method of detecting unauthorized devices using broadband signals for information transmission is that preset the frequency range in which electronic devices can be operated unauthorized, as well as the raw data necessary for measurements. To collect data on a jamming situation, a data matrix is set in which cells record the interference levels measured at successive times, compare the differences in the calculated mathematical expectations with the mean standard deviation for each frequency, count the number of frequencies at which the difference in expectations exceeds the mean standard deviation, compare the number of frequencies with the specified, in accordance with this, a signal is generated about the presence or absence of a broadband signal source in the territory of the monitored facility.

EFFECT: ensuring the detection of unauthorized installed radio electronic devices using broadband signals in a predetermined frequency range, in the absence of preliminary data on the parameters of broadband signals.
