Software and hardware complex for investigation of technical channels of information leakage based on high-frequency irradiation method

The option of creating an information leakage channel using high-frequency radiation (for example, auxiliary technical means or semi-active stowage devices installed indoors) is one of the active methods for obtaining acoustic speech information. This paper provides a rationale for the requirements for technical characteristics and the scheme for constructing a device for detecting high-frequency radiation signals. It serves to develop a software and hardware complex for the study of technical channels of information leakage, based on the method of high-frequency irradiation. The ultimate goal is to create a prototype of a means for detecting and suppressing receiving devices of high-frequency irradiation equipment based on software-defined devices. The paper describes an approach to the creation of the hardware and software parts of the complex, presents the results of studies on the detection of signals in a wide frequency range.
