摘要
讨论了自适应数字波束形成(DBF)技术和超分辨空间谱估计技术,并提出了一种基于信号协方差矩阵特征分解的时-空二维信号高分辨谱估计算法。以上技术应用于相控阵雷达系统,可以精确获得多个运动目标的方位信息和多普勒信息。文章最后给出了计算机模拟结果。
In this paper,the technology of digital beamforming and the high-resolution spatial spectral estimation methods are discussed.An algorithm based on the eigenstructure decomposition of the signal covariance matrix for space-time two dimensional signal spectral estimation is proposed.The presented methods applies to the signal processing of phased array radars and can accurately get the azimuths and Doppler information of multiple spatial moving targets.Finally,the results of computer simulation are given.
