Mutual coupling analysis of collinear antennas with signal and system concept 利用信号与系统概念分析线天线的互阻抗
Antenna mutual impedance 天线互阻抗
Second , we compute the self - impedance through cavity modal theory and mutual impendance based on reaction theory respectively . then the generalized impedance matrix that reflects the effect of mutual coupling is formed . at last , the effect of mutual coupli ng on 2 - d doa estimation algorithms is investigated and two efficient methods of mutual coupling compensation are proposed 本文首先对两种二维doa估计算法? ssm法和二维酉esprit法的性能进行了比较,用空域平滑算法解决了相干源的二维doa估计;其次运用腔模理论计算微带天线的自阻抗,用反应原理计算微带天线间的互阻抗,进而形成计入互耦影响的广义阻抗矩阵;讨论了互耦对二维doa估计的影响,提出了两种互耦补偿的方法。
