摘要
论述了一种基于子空间方法的多信号极化与到达历估计问题的算法。该方法采用了三极子天线均匀线阵,利用子阵列输出信号数据矩阵中包含的信号空间的不变结构,用矩阵柬方法求解出信号极化与到达角的估计值并自动进行参数的配对,避定.了参数的多维搜索配对过程。数值仿真的结果证实了该方法的有效性。
In this paper, a subspace-based algorithm is proposed to estimate both the polarizations and the angles of arrival (AOAs)of incoming plane waves with an uniform linear array oftripoles. Exploiting the inherent invariance structure built in array output data, the correct parameterpoirs can be obtained whiIe avoiding a complicated searching and pairing procedure. Simulation resultsverify the efficiency of the proposed algorithm.
