摘要

基于低轨卫星星座系统的广播自动相关监视(ADS-B)信号接收已逐渐成为空域交通管理的一种重要技术手段。本文通过建立卫星接收ADS-B系统模型，从理论上分析了系统性能与ADS-B接收机灵敏度等因素之间的关系。理论分析和仿真结果表明，基于低轨卫星星座的ADS-B接收系统的终端位置更新速率主要取决于ADS-B接收机的接收性能、星座系统的重叠覆盖数和波束覆盖范围内的终端数;当帧性能优于1×10-1时，增加星座系统的重叠覆盖是提高系统容量的最有效途径。

Performance Analysis of ADS-B Receiving System Based on LEO Satellite Constellation

Automatic Dependent Surveillance-Broadcast (ADS-B) signal reception based on low-orbit satellite constellation system has gradually become an important technical method of airspace traffic management. In this paper, by establishing the satellite receiving ADS- B system model, the relationship between the system performance and the ADS-B receiver sensitivity and other factors is theoretically analyzed. Theoretical analysis and simulation show that the terminal position update rate of the ADS- B receiving system based on the low-orbit satellite constellation is mainly determined by the receiving performance of the ADS-B receiver, the number of overlapping coverage of the constellation system and the number of terminals within the beam coverage; When the frame performance is better than 1×10-1, increasing the overlap coverage of the constellation system is the most effective way to improve the system capacity.
