FIELD: information protection.
SUBSTANCE: protecting information from leakage through technical channels. When probing the environment of the possible placement of technical channels with a spatially localized ultra-wideband pulse signal, the oscillatory circuits that are part of the radio traffic devices are pre-excited by probing the surfaces of the protected room with a package of pulse signals with high-frequency filling, while the lower and upper frequencies of the high-frequency filling pulse signals are set equal to the lower and upper frequency of the operating range of the radio traffic devices, in addition, the frequencies of the high-frequency filling of each pulse are spaced relative to each other by the width of the signal spectrum of the traffic device.
EFFECT: ensuring the localization of technical channels of information leakage created by radio traffic devices.
