摘要
星基ADS-B系统是一种覆盖全球的新型空中交通监视系统。为了评估星基ADS-B系统的监视性能,本文给出了星基ADS-B系统等模型,并以此为基础设计了星基ADS-B系统模拟软件,利用计算机模拟得到了不同空中交通流量场景下的ADS-B消息正确接收概率和95%空中位置消息更新间隔等性能参数。结果表明:共信道干扰会影响系统监视性能,导致ADS-B消息正确接收概率降低和95%位置消息更新间隔增加。
Satellite-based ADS-B system is a new form of air traffic surveillance system which works anywhere.To evaluate the monitoring performance of satellite-based ADS-B system,in this work,the model of satellite-based ADS-B system is proposed and the simulation software of the satellite-based ADS-B system is designed.The software can acquire the performance parameter of satellite-based ADS-B system,such as the correct probability of message reception and 95% position message update interval.The results show that the common-channel interference worsen the system that reduce the correct probability of message reception and increase 95% position message update interval.
