Abstract
Methods of detecting false signals of the automatic identification system of unmanned aerial vehicles against the background of ship signals
Incoming article date: 07.03.2023The operation of unmanned aerial vehicles (UAVs), as well as their compactness and ease of use, allow them to be actively used in various conditions and situations. UAVs have a number of parameters, from remotely piloted to fully automated, including the degree of their autonomy, as well as design and purpose. AIS transponders receive and process AIS signals, receiving at the output messages about the name of the vessel, data on the course, speed and current navigation status with the display of its location on an electronic map. The use of an open data transfer protocol in AIS makes it vulnerable when false signals (LS) appear in traffic containing distorted information with the display of false targets on the screens of AIS monitors, which can lead to navigation accidents. The purpose of the article is to develop proposals for the detection and identification of AIS UAVs. The paper analyzes the possibility of the formation of an AIS UAV, considers approaches to solving the problems of detecting and identifying drugs and suggests methods for their implementation of technical analysis of radio signals.
