METHOD FOR CONCEALED SUPPRESSION OF EAVESDROPPING DEVICE, CONTAINING LOGICAL ELECTRONIC COMPONENTS Russian patent published in 2007 - IPC H04K3/00 

FIELD: radio engineering.

SUBSTANCE: in accordance to method for concealed suppression of eavesdropping device containing logical electronic components, based on generation of electric signal, emitting of it by antenna directed towards eavesdropping device, and due to this inducing electrical interference in electronic circuits and components of eavesdropping device, signal is generated in form of single impulse, for which generator of single impulses is used, while duration of impulse is selected in ranges of nano- or sub-nanosecond durations in accordance to condition of achieving maximally possible peak impulse power for used generator. To select polarity of generated electric impulse, current distance from antenna to eavesdropping device is measured, compared to previously determined limit distance and if distance is less than impulse is generated in mono-polar form, and if distance is greater - in bi-polar form.

EFFECT: increased period of suppression of eavesdropping device compared to period of electromagnetic radiation, and also increased radius and increased probability of suppression.
