摘　　要：本文研究共点放置极化敏感二维正交矢量天线导向矢量(PACS)中隐含的秩-1模糊问题。论文首先定义了同维数但具有不同形式的PACS之间的两种等价关系,在此基础上分析和讨论了几类典型二维PACS的秩-1模糊。研究结果表明,在没有任何先验知识的情况下,使用单个二维正交矢量天线并不能完成单个信号源二维角度和极化参数的唯一辨识。In the paper, we investigate the rank-1 ambiguity problem involved in the polarization-angular coherence structure （PACS） of a two-dimensional co-localized vector antenna whose elements are orthogonally oriented. We define two kinds of equivalence relations under which several typical and easy-analyzed 2-D PACSs are studied.The present analyses also show that with only one 2-D vector antenna DOA and polarization of even one signal can not be uniquely determined.
