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.Third, the challenges and countermeasures of unmanned technology applied to coastal defense islands and border defenseUnmanned science and technology: a new boost to coastal defense islands and border defense.
