2. Task execution in dangerous environmentFirst, the frontier development and multiple capabilities of unmanned technologyUAV plays an important role in coastal defense islands and border defense. In coastal defense, UAV can cruise over the vast sea area of China for a long time, and use its advanced optical and radar equipment to monitor the activities of ships at sea. For example, it can timely find those ships that illegally intrude into China's waters, whether they are small fishing boats or large cargo ships. According to military experts, the cruising efficiency of drones is several times that of traditional patrol ships. In border areas, drones can cross rugged mountains and deserts to monitor the border. Its high-resolution camera can clearly identify abnormal activities such as people and vehicles on the border, which greatly improves the scope and accuracy of border monitoring.
