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Zynq7000设计了一种对广播式自动相关监视(Automatic Dependent SurveillanceBroadcast,ADSB)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ADSB短报文信号。据此,此接收系统可被认为是一种性能良好的ADSB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 surveillancebroadcast(ADSB) signals is designed based on the radio frequency(RF) frontend chip AD9361 and the baseband data processing chip Zynq7000.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 signaltonoise ratio(SNR) is above 6 dB;in actual monitoring,the receiver successfully receives and demodulates the ADSB short message signal with 4.4 dB SNR. Accordingly,this system can be regarded as a good performance ADSB signal receiver. |
