摘要:
为了及时获取航迹信息,基于射频前端芯片AD9361以及基带数据处理芯片Zynq7000设计了一种对广播式自动相关监视(Automatic Dependent SurveillanceBroadcast,ADSB)信号解调的软件无线电接收系统,给出详尽的硬件框架设计,进行了Linux平台搭建,并完成了AD9361寄存器配置工作。经测试,在信噪比6 dB以上时,接收系统的检测概率超过60〖WT《Times New Roman》〗%〖WTBZ〗;实际监测中,接收系统成功接收并解调信噪比为4.4 dB的ADSB短报文信号。据此,此接收系统可被认为是一种性能良好的ADSB信号接收系统。

Abstract:
In order to obtain track information in time,a software defined radio(SDR) receiving system that demodulates automatic dependent surveillancebroadcast(ADSB) signals is designed based on the radio frequency(RF) frontend chip AD9361 and the baseband data processing chip Zynq7000.The detailed hardware framework design is provided,the Linux platform is built,and the AD9361 register configuration is completed. The test proves that the detection probability exceeds 60〖WT《Times New Roman》〗%〖WTBZ〗 when signaltonoise ratio(SNR) is above 6 dB;in actual monitoring,the receiver successfully receives and demodulates the ADSB short message signal with 4.4 dB SNR. Accordingly,this system can be regarded as a good performance ADSB signal receiver.
