METHOD FOR DYNAMIC DETECTION OF SMALL-SIZE HIDDEN FACILITIES THAT FACILITATE INFORMATION LEAKAGE AND ARE INSTALLED ON MOBILE OBJECT WITHOUT AUTHORISATION Russian patent published in 2013 - IPC G01R29/08 

FIELD: measurement equipment.

SUBSTANCE: method for dynamic detection of small-size electronic devices that are installed on a mobile object without authorisation, consisting in the fact that a database is generated on spectra of available authorised electronic devices installed on the object, electromagnetic signals are received in the specified range of frequencies to a single radio receiving device, they are amplified, spectral components of received signals are identified, identified spectra are compared with previously formed spectra in the data base of devices installed on the object as authorised, used on the object of control, the decision is made on availability of special electronic devices. At the same time the distance is set, outside of which signal reception is excluded, the quantity of auxiliary facilities is set for detection of electromagnetic signals of other electronic devices, the main facility is installed for detection of installed electronic devices installed without authorisation, the object is moved, the distance is measured between the auxiliary facility of detection and the mobile object, the measured distance is compared with the set one. A channel of remote control and synchronisation is produced between the main and auxiliary detection facility, electromagnetic signals are simultaneously measured by the main and auxiliary facilities of detection, signals are sent, which have been received by the auxiliary detection facility, to the main detection device along the produced channel of the remote control and synchronisation.

EFFECT: increased validity of detection of unauthorised installed devices and expansion of application area.
