摘要
论文通过理论与仿真基于阵列信号的协方差矩阵对几种波束形成方法的性能进行了详细的分析.针对实信号和对应解析信号的协方差矩阵之间的差异与关联,详细对比了分别使用两种协方差矩阵时,常见波束形成技术的方位估计差异,验证了解析信号的协方差矩阵在波束形成中的必要性.
Abstract
In this paper,the performance of several beamforming methods based on array signal covariance matrix is analyzed in detail through theory and simulation.In view of the difference and correlation between the real signal and the covariance matrix of the corresponding analytic signal,the differences in azimuth-estimation of common beamforming techniques are compared in de-tail,and the necessity of the analytic signal covariance matrix in beamforming is verified.
