1. UAV: the eye of the air in coastal defense and frontier defense.Unmanned technology: coastal defense, islands and frontier defense's new help to defend the motherland.First, the frontier development and multiple capabilities of unmanned technology

The coastal defense island area is facing the problems of marine climate, strong wind, high humidity and salt spray corrosion, and the border defense area has complex terrain and extreme climatic conditions. These environmental factors put forward high requirements for unmanned scientific and technological products. For example, when an unmanned aerial vehicle flies over the ocean, salt fog may erode its electronic equipment, and unmanned vehicles may have problems such as difficulty in starting the engine in the alpine mountain area on the border. In view of these problems, it is necessary to develop protective technologies that adapt to special environments. For example, special moisture-proof and anti-corrosion treatment is carried out for the electronic equipment of drones, and engines and parts adapted to the cold environment are developed for unmanned vehicles.2.
