SIMULTANEOUS COMPENSATION FOR CHANNEL MISMATCHING AND MUTUAL COUPLING IN SPATIAL ESTIMATION
-
摘要: 在空間譜估計(jì)測向系統(tǒng)中,各接收通道中的幅相失配和天線陣元間的互耦是導(dǎo)致測向精度和分辨率下降的主要原因。本文分析了這兩種因素影響測向系統(tǒng)性能的機(jī)制,提出了一種可一次性補(bǔ)償接收通道的幅相失配和陣元間互耦的有效方案。

Abstract: 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. -
