摘要: 研究了单矢量天线的滤波问题.为了充分利用信号和干扰的空域、频域和极化域信息,提出了LCMV准则下的空频极化域联合滤波新方法,当信号和干扰在任何一个域中有差别时,该滤波方法都能更好地抑制干扰,提高输出信干噪比.通过比较可知空频极化域联合滤波方法比空域极化域联合滤波方法的性能要好.

Abstract: We propose a novel algorithm for joint filtering in spatial, spectral and polarizational domains with an electromagnetic vector sensor(EVS). The proposed algorithm can make full use of the information in three domains and signals can be resolved from the interference background provided there is a separation between signals and interferences in any domain. Finally, the validity of this algorithm is verified by simulation results.

Key words: vector sensor, polarization, filter, LCMV
