摘要:

互耦效应导致阵列天线单元间耦合能量的矢量和随扫描角而变化,本文结合等效网络和感应电动势法,通过求出互阻抗求解互耦系数实现互耦误差的校正,仿真结果表明,这种技术可以正确的估计来波方向,且计算量较小。

Mutual coupling effects lead to the coupling energy vector between antenna units changing with the scan angle. For antenna array mutual coupling analysis, signal direction can be correctly estimated by solving the mutual coupling matrix and putting mutual coupling matrix solution into the wave direction of arrival estimation correction formulas combined equivalent network knowledge and induced electromotive method. The simulation results show that signal direction can be correctly estimated and computation is small.
