摘要/Abstract

摘要：

提出了1种针对恒模信号的波达方向和阵列天线互耦系数的联合估计算法。新算法不需要方位已知的辅助校正源，可以在线完成实际信源的方位估计。仿真结果证明了新算法的估计精度取决于信源的信噪比、方位组合和快拍数等因素。

关键词: 阵列天线, 非线性约束, 误差校正

Abstract:

A union estimation algorithm is presented to estimate DOA of CM signal and mutual coupling coefficient of array antennas. The new algorithm does not need the assistant calibration sources that directions are known and may estimate direction of actual source online. Simulation results show the accurary of the new method depends on snapshots and the direction combination and SNR of signal sources.

Key words: Array antennas, Nonlinear constraint, Error calibration
