| 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. |
