摘要
论述了无源雷达中实现多波束数字波束的方法。阐明通道幅相误差的构成,指出幅相一致性对波束形成的影响,提供了校准通道和评估形成波束的实用方法。给出了在Champ-av3主板上实现多波束DBF的硬件框图和软件流程。
In this paper , realization of multi-digital beamforming in passive radar is described. Clarify the combination of amplitude-phase error in channels, Point out the effect of consistent amplitude-phase in beamforming, offer the practicably methods of adjust channels and evaluate actual beam figure . Block diagrams of software and hardware based on Champ-av3 board are given.
