摘　　要：提出了一种基于ESPRIT矩阵束法的UWB雷达目标特征提取方法,该方法把提取信号极点问题转化为求解矩阵束的广义特征值问题。理论分析和数值仿真结果表明,这种方法与传统的Prony算法相比有明显地改进,能有效地提取出目标回波信号的极点和留数,并对随机噪声具有良好的抑制作用。该方法特别适用于UWB雷达或其它高分辨率雷达的目标特征提取。A new method, ESPRIT matrix pencil algorithm, is introduced for extracting UWB radar target feature. The problem of extracting signal poles is translated into the problem of calculating general eigenvalues of matrix pencil using this method. Theoretic analysis and simulation results show that this method is an improvement upon conventional Prony method. The poles and residues of target echo can be extracted effectively using this method, and random noises are restrained in some degree. It is applicable to target feature extraction such as UWB radar or the other high resolution range radar.
