一种基于AD9361的ADS-B多目标信号源设计

A multi-target ADS-B signalsource based on AD9361

多目标信号源对设备实验室研发阶段的系统测试至关重要。当前市面上多数的信号源只能下载单一类型信号,或者时域上基带合成的信号。笔者根据多年嵌入式的设计经验结合当前成熟的射频频率捷变芯片AD9361提出了在射频域上完成多路ADS-B信号合成的设计思路,该方法可根据用户需求完成相应数量的多目标信号合成。最后提出采用ZYNQ和AD9361结合的架构完成该信号合成算法设计的整体思路,大大降低了信号源设备的体积和功耗,节约了成本,加快了设备的研制周期。

Multi-target signal source is crucial to system testing in the equipment research and development.Most of the signal sources on the market can only download a single type of signal or synthesized baseband signal in the time domain.Based on years of embedded design experience,combined with the current sophisticated RF frequency agility chip AD9361,a multi-channel ADS-B signal synthesis method is designed on the RF domain,which can complete the corresponding number of multi-target signal synthesis according to user's needs.Finally,the overall idea of using ZYNQ and AD9361 to realize the signal synthesis algorithm is proposed,greatly reducing the size and power consumption of the signal source equipment,saving the cost,and accelerating the development cycle of the equipment.
