摘要

介绍了一种用于接收机的波束形成样机的设计和特性分析结果。四通道系统使用交换光纤延迟线，信号在单个检测器上添加之前进行光学组合。已经测量了101 dB/spl的中点/Hz/sup 2/3/的SFDR，这是很好的，使用低功率直接调制激光二极管。

Photonic true time delay beamformer demonstrator for a radio astronomical array antenna

The design and characterisation results of a prototype beamformer for receive application are presented. The four channel system uses switched fibre delay lines and signals are combined optically before addition on a single detector. An SFDR of 101 dB/spl middot/Hz/sup 2/3/ has been measured, which is good, given the use of a low power directly modulated laser diode.
