Innovative Methods of Terahertz Diagnostics in Selected Key Military and Security Applications

Abstract

The article presents the main research directions of the project implemented by the consortium under the National Defence and Security Program: "Development of modern, breakthrough technologies for state security and defence", codename "SZAFIR". During the implementation of the project, the possibilities of using terahertz radiation will be examined for diagnostic tests of components crucial for defence and security, such as solid rocket fuels, aramid fibre-based composites (bulletproof vests, helmets, pyrotechnic suits), and polymer composites reinforced with glass and carbon fibres (aircraft elements). As a result of research, the interaction of tetheric radiation with materials of these components will be analysed, followed by the development of a methodology for determining their defects. This will result in creating innovative dedicated stations for non-destructive testing of these components. Neural network-based advanced signal processing and artificial intelligence algorithms will be used for automatic diagnostics of key components, improve the process of their control and therefore increase the safety of people and military equipment.
