摘要:
广播式自动相关监视(Automatic Dependent Surveillance-Broadcast,ADS-B) 是安全、高效的空中交通监视手段。 针对安装全向天线的 ADS-B 地面站存在航迹掉点问题,提出了一种四通道定向天线的 ADS-B 地面站的模型。 首先,从站点和环境等多角度初步判定大量的空域信号交织干扰会造成信道拥挤、多重信号交织;然后,通过对信号实时捕获、现场录取数据等进行航迹确认;最后,建立目标交叠模型验证空域交叠信号与 ADS-B 航迹掉点的相关性。 实验结果表明,空中存在大量的空域应答信号交织干扰情况,最终造成信道拥挤、多重信号交织而导致信号解码率下降,因此产生 ADS-B 掉点现象,多通道天线在一定情况下可改善 ADS-B 地面站性能,解决航迹掉点问题。
Abstract:
Automatic Dependent Surveillance-Broadcast is a safe and efficient air traffic monitoring method. Aiming at the track dropproblem of ADS-B ground station with omnidirectional antenna,a model of ADS-B ground station with four-channel directional antennais proposed. Firstly,it is judged from multiple perspectives such as site and environment that a large number of spatial signal interleavinginterference will cause channel congestion and multiple signal interleaving. Secondly,track confirmation is through real-time capture ofsignals and on-site data acquisition. Finally,a target overlap model is established to verify the correlation between the airspace overlapsignal and the ADS - B track drop point. The experimental results show that there are a large number of airspace response signalinterleaving interference in the air,which will eventually cause channel congestion and multiple signal interleaving,resulting in a decreasein the signal decoding rate. Therefore, the phenomenon of ADS - B drop points occurs. Under certain circumstances, multi - channelantenna can improve the performance of the ADS-B ground station to solve the problem of track drop.
