自跟踪和差模极化自适应天线

An auto tracking antenna with adaptive polarizations of the Σmode and Δmode

基于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干扰信号．这对船站卫星通信天线和侦察干扰天线很有价值．文中方法适用于天线阵和圆波导馈源．

Based on the adaptive processing technique, a new idea is presented for an auto tracking antenna with polarization adaption for the Σ mode and Δ mode. The parameters of the components in the feed network are fixed due to the fact that neither microwave or IF variable shifters nor rotating shifters are required. For any polarization incident wave, the antenna is able to not only realize full polarization reception without polarization loss but also transmit an interference signal aligned with the polarization of the incoming wave or orthogonal to it, which is of value to the ship station satellite communication antenna and reconnaissance interference antenna. The method presented is suitable to the antenna array and circular wave guide feed.
