UAVs, characterized by miniaturization, intelligence, accessibility, and diversity, are rapidly growing in various sectors, from consumer drones to industrial applications like power, forestry, and logistics. This growth has led to an increase in security incidents and terrorist attacks.

In major events, such as international conferences, sports events, celebrations, etc.,the irregular flight or malicious intrusion of drones will bring serious safety risks. These activities often involve a large number of people gathering, the transmission of important information, and the protection of sensitive areas, and the issue of drone defense cannot be ignored.

In the petrochemical industry, UAVs present two significant risks. Firstly, they can be utilized as reconnaissance tools to gather intelligence on critical facilities, potentially facilitating sabotage activities. Secondly, during the operation of oil and gas fields, as well as refining and chemical processes, flammable and explosive gases are often produced. An accidental UAV intrusion could trigger catastrophic accidents, leading to severe casualties and substantial economic losses.
