无人机系统自主安全: 定义、建模与分级

The balance between autonomy and safety is the strategic demand and key for the rapid development of unmanned aerial vehicle (UAV) technology and industry. In the face of “continuously improving unmanned autonomous flight capability” and “increasingly severe physical, information, intelligence, and other multidomain security threats,” the traditional security architecture with fit-to-fly and sense-and-avoid technologies as the core cannot meet the safety and security requirements of current and future UAVs only by referring to the manned aerial vehicle safety system. It is necessary and urgent to construct a new UAV autonomous safety and security architecture in multiple domains. Starting from the inherent essential attribute of autonomy in UAVs, the autonomous safety and security architecture of UAVs is studied in this paper, concentrating on the definition and characterization of the new concept “autonomous safety and security of UAVs,” constructing a new autonomous safety and security model facing multidomain security threats and proposing the gradation of the autonomous safety and security power. This study would provide basic support for the rapid development of UAV industry and a reference for establishing security systems for other unmanned systems.
