摘　　要：针对微小型飞行器自主独立完成对运动目标实时动态追踪的问题,本文提出一种新型目标自主追踪方法。该方法基于欧拉法的改进方法预测—校正法预测运动目标实时运动状态和位置,而后采用比例导引和速度追踪的联合方法实现快速接近追踪目标、精确调整运动状态及稳定跟踪目标3个步骤,完成运动目标的自主实时追踪。将其应用于目标追踪过程中,在仿真步长为0.25s时,算法追踪位置误差小于0.025m。可见利用这种新型方法能够有效实现对运动目标完全自主的实时稳定跟踪与探测。A method for micro air vehicle （MAV） which automatically tracks the maneuvering target is proposed in this paper. This method based on the improved Euler method known as predict-correct method to obtain the real-time motion status and location of the target, then joint methods of proportional navigation and velocity tracing method are used to make the MAV approaching the target quickly, adjusting the status precisely and keeping tracking stably. When the simulation steps is 0. 25 s, algorithms track position error is less than 0. 025m. Therefore, the target tracking can be effectively completed by using this method and simulation results can serve as important reference for practical application.
