【摘要】 本文讨论了利用电磁波的三维极化信息决定其到达方向的问题。提出了一种在CDMA体制下利用扩频——解扩方法从复合波场中区分单独信号波场的极化信息,从而决定各个信号的各个多径分量的到达方向的方案,并提供了数字实例。同时,本文还提出了分层圆周阵列天线的构想。这种阵列的每一层动态地分配给一个特定的移动台,以一个主瓣灵活而方便地跟踪该移动台。更多还原

【Abstract】 In this paper the issue of utilizing polarimetric information of EM waves to determine their DOA at a cell station is investigated. An approach is adopted employing spreading and de-spreading methods under CDMA format to recover individual wave polarization from a composite wave field, and a numerical example is given which is shown workable. Besides, a multi-layer circularly aligned array is conceived. Each layer of the array is dynamically allocated to a specified mobile station with its main lobe tracking the mobile user flexibly and conveniently.更多还原
