面对飞行流量持续快速增长，民航空域资源日益短缺，对冲突飞机进行有效的解脱，是避免飞机间发生碰撞的关键技术。对飞机保护区域进行合理建模，给出一种基于广播式自动相关监视（ADS-B）技术的冲突解脱算法，该算法有效利用ADS-B的数据精度高、更新快的特点，从水平方向上给出“保向变速”与“保速变向”两类解脱策略，从垂直方向上给出“爬升”和“下降”两种解脱策略。把飞机的水平速度、航向和垂直速度作为控制变量，通过计算冲突解脱的边界条件获得控制变量转换时间，从而找到可行的解脱方法。仿真结果表明，对于同一飞行冲突情形，并不是所有的冲突解脱策略都是可行的，但是对于可行的冲突解脱策略，需要由飞行员根据当时的具体情况去决定哪种解脱方式是最优的。

With the continued rapid growth of flight traffic and the increasing shortage of civil aviaton airspace resource, to implement the collision avoidance between aircrafts effectively is the key technology to avoid aircrafts collision. A model for the aircraft protecting zone is reasonable constructed and a collision avoidance algorithm based on ADS-B is proposed. This algorithm make full use of the characteristics of high precision and high-speed update rate for the ADS-B message, propose two types of the collision avoidance strategy of”Keep speed is constant, and change direction”and“Keep direction is constant, and change speed”from horizontal direction and two kinds collision avoidance strategy of “climb” and “descend” from vertical direction. Using the horizontal velocity,direction and vertical speed as control variables, the conversion time of the control variable through the calculation of boundary conditions is obtained, thereby the feasible resolution method is founded. The simulation results show that not all conflict resolution strategy is feasible for the same flight conflict situations, it need to choose the most optimal collision avoidance pattern according to specific situation by pilot from the feasible resolution strategy.
