本文介绍了一种利用光学纤维作相控阵天线波束成形装置延迟线的电—光技术.已构成的功能试验可行性验证装置,可同时形成三个独立波束,用于八元线性相控阵天线,设计的该装置的瞬时带宽为2GHZ(工作频段为2～4GHZ).
This paper presents an electro-optical technique using optical fiber as a delay line for a phased array antenna beamformer.The functional test feasibility verification device has been constructed to simultaneously form three independent beams for an eight-element linear phased array Antenna, the device designed for the instantaneous bandwidth 2GHZ (working frequency band 2 ~ 4GHZ).
