Aiming at the issue of autonomous path tracking and obstacle avoidance of aircraft, in order to suppress the significant change of the speed direction during the path tracking process, the terminal angle constraint item is introduced into the guidance law to realize the smooth tracking of each path point. In addition, based on the relative positional relationship and movement direction between the aircraft and the obstacle, the obstacle avoidance guidance law is established in the target line of sight coordinate system in this paper. At the same time, the speed control item in the process of avoiding obstacles has been added. Through simulation, the aircraft which manipulated by the guidance law can achieve smooth tracking of the preset path and effectively avoid unexpected obstacles in the path as well.
