A system for destroying FPV drones controlled via fiber optic communication lines using barriers with pulsed electric discharge

Abstract

This article describes an innovative approach to countering FPV drones equipped with fiber-optic communication systems by creating high-temperature electro-thermal barriers. The methods for destroying the fiber-optic cable are based on heating or pulsed discharges, which cause the fiber to burn upon contact with a conductive wire. Two technologies are compared: constant heating of a nichrome wire and pulsed high-current discharges of steel wire. The technical implementation of the system is provided, including energy storage, high-voltage switches, and controllers, enabling the creation of modular protection networks for rear facilities. An analysis demonstrates the advantages of pulsed systems, particularly their masking, efficiency, and the potential for long sections. The choice of materials and circuit design for creating localized high-temperature destruction zones of optical fibers is justified. The proposed technology offers promising prospects for developing passive, safe, and scalable means of protecting objects from next-generation unmanned systems that utilize fiber-optic control channels.
