| 摘 要： | 首先用矩量法精确分析了考虑互耦影响时天线阵元的电流分布,给出了计算电流的解析式,并仿真计算了单元直线阵的电流分布。然后以等效网络法为基础研究互耦影响存在时修正MUSIC算法的DOA估计性能,仿真实验表明在互耦影响存在时MUSIC算法失效,而修正MUSIC算法仍然具有良好的DOA估计性能。

| Abstract: | In this paper, the distributing of current in array antennas with the effect of mutual coupling is accurately analyzed with MOM. Analytical expression of current is presented and the distributing of current of linear array of eight ideal dipoles is simulated. Then, the performance of DOA estimae of modified MUSIC algorithm is studied with the method of Equivalent Network. Simulation indicates that the performance of estimate DOA of the MUSIC algorithm is disabled in the presence of mutual coupling ,but the modified MUSIC algorithm is also good. |
