IMPROVED METHOD OF ASSESSING THE SECRET OF FUNCTIONING OF RADIO TECHNICAL EQUIPMENT

Abstract

Modern radio engineering systems are characterized by the use of radio waves with a complex internal structure as information carriers. Such radio waves are characterized by an increased transmission spectrum width and programmed pseudo-random tuning of the operating frequency. Along with this, signals with an increased transmission spectrum width are related in their characteristics to white noise signals, which reduces their electromagnetic availability of electronic intelligence systems. So, the article presents an improved methodology for assessing the secrecy of the functioning of radio technical means of a military communications system, built on radio communications, which use a complex structure of a transmission signal as an information message. The main criterion for assessing the secrecy of the functioning of radio technical means was chosen the indicator of the energy secrecy of transmission signals, namely, the indicator of electromagnetic availability. Taking into account the indicator of the electromagnetic availability of radio emission sources with complex signals makes it possible to more realistically assess the secrecy of the functioning of radio equipment of the military communications system, in turn, determines the factors for making informed decisions regarding the choice of operating modes of radio communications in order to conceal the functioning of the elements of the military communications system.
