МЕТОДИКА РОЗРОБКИ СЦЕНАРІЇВ РАДІОЕЛЕКТРОННОГО ТА ЕЛЕКТРОМАГНІТНОГО ПОДАВЛЕННЯ НАЦІОНАЛЬНОЇ ТЕЛЕКОМУНІКАЦІЙНОЇ МЕРЕЖІ В УМОВАХ ОСОБЛИВОГО ПЕРІОДУ

Annotation. Interference protection of the communication system is a relevant and important researching area, impact assessment methodology of radio (RS) and electromagnetic suppression (EMS) is rather developed and known for today. The National Telecommunication Network (NTN), as a set of communication systems and networks, in the context of a hybrid war against Ukraine requires protection improvement from the destructive influence of the enemy, which has the latest RP and EMF. Unsecured NTN will not be able to perform its main function, namely the circulation (transmission, reception, creation, processing and storage) and protection of national information resources, providing secure electronic communications, providing a range of modern secure information and communication (multiservice) services in the interests of government in peacetime, in a state of emergency and during a special period. In addition, NTN is a dual-purpose network (system) with partial usage of its resources to provide services, including cyber security, to other consumers. Qualitative development of methods and techniques to ensure interference protection of NTN elements is impossible without predicting possible scenarios of the enemy and the interference situation that may arise.It is proposed to use scenarios approach during adaptive algorithm development of interference protection of special means of communication against active radio and electromagnetic suppression of the enemy in hybrid actions and terrorist activities. The method of substantiation of scenarios of RS and EMS of the transport platform (TP) of NTM and determination of scenarios of complex signal-interference situation is developed. These scenarios are necessary for the further synthesis of adaptive interference protection algorithms of TP NTN.The method allows substantiating the composition and usage of RS and EMS measures of enemy within the timeline and b the elements of TP NTN terms of hybrid war against Ukraine.It is concluded that it is necessary to synthesize the interference protection algorithms of communication channels, which will be adaptive to different scenarios of signaling, and interference situation that may occur.
