• However , the instantaneous bandwidth of signals is restricted for general phased array because of its transition time and aperture effect
  但是,基于移相器的普通相控阵天线在进行宽带宽角扫描时,由于渡越时间和孔径效应的影响,使信号的瞬时带宽受限。
• Due to restriction with the array aperture transition time , traditional phased array radar works under relative narrow signal bandwidth , so this restricts the application of phased array radar in the field where high performance is demanded . however , optically controlled phased array radar ( ocpar ) adopts the photoelectron technology , counteracts the aperture transition time via the method of optical true time delay ( ottd ) , so it can realize wide instantaneous bandwidth and squint - free operation ; meanwhile , it can realize the miniaturization of phased array radar and has super anti - electromagnetism interference capability
  而光控相控阵雷达采用光电子技术,通过光实时延迟的方法来抵消孔径渡越时间,可以实现相控阵雷达的宽带宽角扫描;同时也可以使得相控阵雷达小型化,并具有强的抗电磁干扰的能力;另外,由于光纤传输具有损耗低、频带宽等固有优点,采用光纤连接雷达天线和雷达控制中心,可以使两者的距离较采用同轴电缆有较大的提高,更有利于保护雷达控制中心。
• As ttd ( true time delay ) is utilized in optically controlled phased array at sub - array level to replace the phase shifter in general phased array radar system , and make time delay compensation at sub - array level , which can reduce aperture effect considerably and make the broadband and wide - angle scanning of phased array antennas come true
  由于光控相控阵雷达在子阵级上引入实时延时线ttd ( truetimedelay )取代常规相控阵雷达中的移相器进行子阵级的延时补偿,大大减轻了孔径效应,使相控阵雷达实现了宽带宽角扫描。
