| 摘 要： | 天线阵各通道之间的通道失配（幅相特性不一致）会严重影响阵列信号处理的性能1,2],为此在进行阵列信号处理前必须对各通道的幅相特性进行均衡.本文针对天线阵通道之间与频率无关的恒定通道失配问题,提出了一种基于LMS好地校正与频率无关的通道失配.本算法的易于工程实现的通道校正技术.计算机仿真结果表明,采用这种技术可以很文最后还给出了该算法在VLSI（超大规模集成电路）平台上的实现结构.

| Abstract: | The performance of antenna array signal processing is deteriorated markedly by the mismatch(the variance of gain and phase) among antenna element channels~,and the mismatch must be equalized before array signal processing for getting high performance.A calibration technique based on LMS algorithm has been proposed to the question of antenna array channel mismatch independent of frequency.Computer simulation results show that this technique is corrective and effective.Finally the implementation structure on VLSI(Very Large Scale Integration) has been described in detail. |
