With the continuous advancement of combat-oriented training， a certain number of unexploded ordnance （UXO） may appear on field training grounds. Manual methods for UXO disposal involve high risks and require considerable manpower. Meanwhile， the rapid transformation of operational support in low-altitude airspace environments provides new possibilities for disposing of UXO. This paper mainly introduces UAV-based UXO disposal technology from the perspective of low-altitude UAV operations. It first reviews the current research status of UXO detection， recognition， and neutralization technologies， and then summarizes the existing difficulties and challenges based on an analysis of the full process of UXO disposal. Taking UAV-based UXO disposal as an example， it explores key technologies such as the construction of training range maps， UXO recognition algorithms， and neutralization methods. Finally， it puts forward views on future development， aiming to provide guidance for the application of UXO disposal in subsequent low-altitude combat support.
