利用自适应信号处理方法,提出和差模极化自适应天线的设想。馈电网络中各元件的参数是固定的,不需要使用可变的微波或中频移相器,也不需要旋转移相器。对任意极化来波都能全极化接收,无极化失配损耗,还能发出与来波共极化或反极化的通信或干扰信号.这对船站卫通天线和侦查干扰天线很有价值。本文方法适用天线阵和圆波导馈源。
Using the adaptive signal processing method, the idea of differential mode polarization adaptive antenna is proposed. The parameters of the various elements of the feed network are fixed and do not require the use of a variable microwave or intermediate frequency phase shifter or the need to rotate the phase shifter. For any polarization of the wave can be fully polarized receive, non-polarization mismatch loss, but also with the incoming wave co-polarization or polarization of the communication or interference signals. valuable. This method is suitable for antenna array and circular waveguide feed.
