ENHANCING THE LEVEL OF PROTECTION AND VIABILITY OF UNMANNED AVIATION DEVICES

Abstract

With the modern development of information technology, remote control devices are becoming increasingly widespread. Their proliferation is primarily due to their main advantage - the ability to conduct observations or perform certain operations in places that are dangerous or completely unsuitable for human presence. One such application is the use of unmanned devices during military operations, which allows the operator to be in relative safety. Such use of unmanned systems, in turn, encourages the creation and development of methods to counter these systems, disabling communication and control channels, or detecting and locating the operator’s location. For this, there is a wide range of electronic intelligence tools, electronic warfare, direction finding stations, etc. The object of this study is the task of increasing the level of protection of unmanned devices and complexes against enemy electronic warfare means and the task of restoring communication and functionality of the device in case of failures in its operation due to accidental obstacles or actions of the attacker. The article contains a brief overview of modern methods and means used to ensure the protection of radio transmissions and analyzes the possibility of their application in small unmanned aviation systems, which are now most used by the military at the current stage of confrontation with the enemy. Based on this, a method of implementing communication protection measures to restore the functionality of the unmanned device was proposed, the principle of its operation is described. The main relevant problem underlying the study is the insufficient protection of communication and navigation systems in civilian solutions and electronic devices that are now actively used to build unmanned vehicles used in military and reconnaissance operations. The obtained results will allow to increase the protection of unmanned systems by applying frequency retuning means to improve the stability and reliability of communication in UAV control systems.
