摘　　要：在空间谱估计测向系统中,各接收通道中的幅相失配和天线阵元间的互耦是导致测向精度和分辨率下降的主要原因。本文分析了这两种因素影响测向系统性能的机制,提出了一种可一次性补偿接收通道的幅相失配和阵元间互耦的有效方案。The performance of the high resolution direction finding technique based on the spatial spectrum estimation is severely suffered with channel mismatching and mutual coupling between elements in arrays. In this paper, the mechanism of performance degradation due to above mentioned factors is analysed, and an effective method of compensation for channel mismatching and mutual coupling is proposed.
