摘要: 建立了频率、二维到达角和极化联合估计的阵列误差信号模型,分析了阵列误差对用ESPEIT算法进行参数估计性能的影响。推导了在阵列误差模型下,频率、二维到达角和极化联合估计算法中各参数估计结果的均方误差。计算机模拟结果证实了分析结果的正确性。Abstract: The array error model of joint frequency, two-Dimensional Angles of Arrival (2-D AOA) and polarization estimation is constructed. The paper then analyzes the parameter estimation performance of the algorithm based on theoretical conditions under array error and deduces the Mean-Square Error (MSE) of frequency, 2-D AOA and the polarizations. From the computer simulation we can see that the theoretical results and the simulation are similar.
