Unmanned science and technology: a new boost to coastal defense islands and border defense.There are many dangerous environments and tasks in coastal defense islands and border defense work. For example, maritime patrols in bad sea conditions, patrols in disputed border areas, etc. The application of unmanned technology can make people avoid directly facing these dangers. Unmanned aerial vehicles can patrol the sea area in front of storm warning, and unmanned vehicles can patrol the border minefield, which greatly reduces the risk of casualties and ensures the task.3. Efficient logistics support needs

UAV 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.China has a long coastline, numerous islands and vast land borders, and it is difficult for traditional monitoring methods to cover these vast areas. Unmanned technology can solve this problem well. Drones and unmanned devices can extend the monitoring range and fill the dead ends of monitoring. No matter in the waters around distant islands or in the inaccessible border mountainous areas, unmanned technology can continuously monitor and ensure that China's coastal defense islands and border defense areas are always under monitoring.2.
