Abstract

In low altitude airspace, Unmanned Aerial Vehicles (UAVs) often face many security threats, which pose enormous challenges to the development of low altitude industries and the construction of low altitude economies. This paper analyzes the main security risk factors from the perspectives of UAVs flight physical failures, low altitude early warning detection network, UAVs communication link defects and information security threats, among which the related threat issues are briefly discussed, such as poor flexibility of UAVs flying on fixed routes, vulnerability to attack during approach reconnaissance, electromagnetic interference emitted by low altitude defense systems and the change of flight control right of Wi-Fi link signals and onboard flight control systems. The results of this paper are helpful for the safety risk assessment of UAVs.
