针对宽带信号无法采用移相器实现分布式接收,提出一种基于时延控制的分布式接收技术,并推导分布式接收信噪比与通道数之间的关系。进一步理论分析通道误差对分布式接收性能的影响,仿真试验表明,理论结果与试验结果一致,且影响分布式接收性能的主要因素是通道数和通道的时延误差。
In view of the wideband signal can not use the phase shifter to achieve distributed reception, a distributed receiving technique based on delay control is proposed and the relationship between the distributed received signal-to-noise ratio and the number of channels is deduced. The influence of the channel error on the distributed reception performance is further analyzed theoretically. The simulation results show that the theoretical results agree well with the experimental results, and the main factors affecting the distributed reception performance are the number of channels and the delay error of the channel.
