摘要
本文利用具有窄带引导信号的ＬＭＳ算法估计柔性天线阵各阵元的相位，能够自适应地确定时变的控制矢量，可以为动态波束形成提供阵形信息。文中提出了求解各阵元坐标的两种算法，经计算机仿真及对实际数据的处理结果表明，所用方法算法较简洁、所需条件较易得到满足，可以满足一般阵处理技术中对阵形估计的精度要求．
This paper deals with the estimation of elements phase using LMS algorithm with a narrow-band pilot signal, the algorithm can determine a time-varying steering vector adaptively and provide array shape information for beamforming. Two algorithms to solve elements coordinate are given. The results of computer simulation and real data processing show that the algorithm used in this paper is simple and necessary condition can be obtained easily. The results also show that the algorithm can satisfy the precision needed for the estimation of array shape in general array processing technology.
