This article analyzes the development stage of Unmanned Aerial Vehicles (UAV) based on its main technical characteristics, and prospects its intelligent trend. Firstly, by analyzing the development history and main characteristics of UAVs for more than a hundred years, the UAV development is divided into the initial stage (1917-1963), the preliminary development stage (1964-1990), and the rising development stage (1991- 2000), vigorous development stage (2001-2010), steady development stage (2011-present) and intelligent development stage. Secondly, multi-dimensional analysis and comparison of the characteristics of each stage from the perspectives of main characteristics, mission tasks, task loads, navigation systems, control methods, etc. Finally, the intelligence trend of UAVs is analyzed from three aspects: the intelligence of single unmanned systems (cognitive intelligence), the intelligence of unmanned cluster systems (swarm intelligence) and the intelligence of man-unmanned systems (hybrid intelligence).
