一种采用ADS-B技术的通用航空防撞系统

A Collision Avoidance System for General Aviation Based on ADS-B

为适应快速发展的通用航空对避撞的迫切需求,在基于广播式自动相关监视(Automatic Dependent Surveillance-Broadcast,ADS-B)的通用航空监视系统的基础上构建了通用航空防撞系统,该系统与无人机和运输航空一体化构建。结合ADS-B工作范围广和通用航空防撞复杂的特点,提出并构建了包括紧急避撞、一般避撞和提前避撞的三级避撞系统。分析了避撞系统中区域的划分,给出了避撞处理流程,讨论了每一级避撞需求及其关键算法。

In order to adapt to the urgent need of the rapid development of general aviation,a general aviation anti-collision system is built on the basis of the general aviation surveillance system based on automatic dependent surveillance-broadcast(ADS-B),which is integrated with unmanned aerial vehicle(UAV)and transportation aviation.According to the characteristics of wide work scope of ADS-B and complex anti-collision of general aviation,a three-level collision avoidance system is proposed and constructed which includes emergency collision avoidance,general collision avoidance and early collision avoidance.The division of area in collision avoidance system is analyzed,the process of collision avoidance is given,and the demand for collision avoidance and the key algorithm are discussed.
