DEVELOPMENT OF SECURITY SYSTEM SCHEMES OF DISTRIBUTED TYPE PERIMETERS BASED ON FIBER OPTICAL TECHNOLOGIES

   This article discusses the development of distributed type perimeter protection systems based on fiber-optic technologies for special facilities and other facilities of national importance against unauthorized access. The analysis of existing systems that are already developed by Russian and foreign scientists is given. For consideration, two options are proposed for an energy-passive perimeter security system with high stealth indicators. The main sensor is optical fiber. The measurement principle is based on the control of the magnitude of additional scattering losses due to mechanical stimulus, measured in dB. Research was conducted on laboratory samples of fiber-optic systems for the protection of distributed type perimeters. In conclusion, descriptions of the results of the study using an reflection-coefficient meter are given.
