摘要
干涉仪天线阵单元天线的非理想特性会对极化和到达角的估计带来较大的误差。对单元天线的极化误差进行建模,利用极化相互正交的天线在空间上的对称性,提出一种极化、到达角的联合估计算法。仿真验证表明该算法具有很高的估计精度,并且简单,具有较高的工程应用价值。
The imperfect characteristics of the interferometer array antenna will bring large error in estimation of DOA and polarization. The polarization error on antenna element is modelled, a joint estimation of polarization algorithm is proposed based on the space symmetry of mutual orthogonal polarization antennas. The simulation results show that the proposed algorithm has high estimation accuracy;the algorithm is simple and has a high application value in engineering.
