摘要
针对ADS-B系统在实际使用中所面对的信号交织干扰和欺骗攻击的问题,提出基于阵列天线、阵列信号处理,提升系统在实际电磁环境中运行稳健性的方法。系统通过信号测向、空域波束形成、多通道信号增强,实现信号的空域解交织和时域解交织,实验仿真证明该方法可以在一定的交织干扰和欺骗攻击的情况下,正确提取信号,提升系统运行的稳健性。
In order to solve the problems of signal interlaced interference and spoofing attack faced by ADS-B system in practical use,a method based on array antenna and array signal processing is proposed to improve the robustness of the system in practical electromagnetic environment. Through signal direction finding,spatial beamforming and multi-channel signal enhancement,the system realizes spatial and temporal de-interleaving of array signals. Simulation results show that this method can solve the interleaving interference and spoofing attack under certain conditions.
