　　分析了一种基于数据链的自动空中防撞技术，从空中自动防撞系统需求出发，描述了系统基本工作原理和流程。采用二次曲线拟合方法，给出了最优控制数学模型，以求解无人机航路间的最小距离，实现最优机动操作组合。仿真分析结果表明，空中自动防撞系统可在碰撞发生前的最后时刻有效完成逃逸操作，避免发生飞行碰撞，可为无人机编队提供进近飞行的安全防护。

A method of an automatic air collision avoidance system(ACAS)based on data link is presented in this paper. According to the basic requirements on the Auto-ACAS,the working principle and flow of the system are analyzed. The mathematical model of optimal escape is given by curve fitting both the flight path of two Un-manned Aerial Vehicles(UAVs)with quadratic curves as a function of time,and by finding the analytic solution to the minimum separation distance between two curves. The simulation results indicate that the Auto-ACAS can provide mid-air approaching collision protection for UAVs at the last moment.
