摘要 提出了一种适用于任意阵列的极化和二维DOA联合估计算法。该算法基于信号空时二维结构特征,利用空域采样和时域采样构造时空矩阵,通过DOA矩阵方法进行极化和二维DOA参数估计,不需要二维谱峰搜索,计算量小。仿真实验证明了算法的有效性。 A joint estimation method of polarization and 2D （two-dimensional） DOA was proposed for arbitrary array. Based on the space-time eigenstructure of signals, space-time matrixes were constructed by spatial domain sampling and time domain sampling. The DOA matrix method was utilized to estimate the parameters in this method. It doesn＇t need spectral peak searching and complex computation, The simulation validated effectiveness of this method.
