摘　　要：基于双平行极化敏感阵列,提出了一种部分极化信号频率,二维到达角和极化参数联合估计的算法。该算法能精确地估计出部分极化信号的多维参数,无需多维谱峰搜索,具有计算量小,参数自动配对的优点,而且也适用于含有完全极化信号的情况。另外,算法也能有效地解决信源参数兼并问题。计算机仿真结果验证了算法的有效性。Based on two parallel polarization sensitive arrays, a new algorithm is presented for joint estimation of frequency, 2-D arrival angles and polarization parameters of partial polarized signals. Getting rid of multidimensional spectrum peak search, multidimensional parameters of partial polarized signals are precisely estimated with smaller computational load and parameters paired automatically, and the case including completely polarized signals is adapted too. In addition, it can still estimate correctly parameters of signals when partial polarized signals have the same parameters. Computer simulation confirms its effectiveness.
