Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back The Process of Searching for Places of Intelligence Availability of Parametric Channels of Information Leakage as an Object of Functional Modeling M.P. SYCHEV, A.V. MAZIN, A.M. SYCHEV, E.V. ZELENTSOVA, V.O. KRYLOV This article is the second of a series of articles devoted to the functional representation of actions to intercept electromagnetic radiation (EMR) arising due to changes in the parameters of radioelectronic devices (REU) of a reconnaissance object under the influence of an informative signal and external high-frequency electromagnetic irradiation. It describes a functional model of the first stage of this kind of action - the stage of searching for places of intelligence availability of informative acoustic signals of the object of exploration through channels of acousticelectrical transformations, high-frequency (HF) irradiation, parasitic (auto) generation and HF imposition. The procedure for the functional structuring of this stage to the level of the signs of the functions performed by the violator formed as a result of the implementation of this kind of threat is given. Keywords: functional modeling, parametric channels of information leakage, interception of EMR arising due to changes in the parameters of the PRUE of the exploration object under the infl uence of an informative signal and external high-frequency electromagnetic irradiation.
