| 摘 要： | 本文在对时空DOA矩阵方法进行详细分析的基础上,提出了该方法的几种改进与推广形式.理论分析和仿真结果表明,时空DOA矩阵方法作为一种新的基于信号时空特征结构的高分辨率二维DOA估计方法,可以通过空时二维处理在时空域中衍生出大量虚拟阵元,因此对阵列结构的约束较松,能够根据需要灵活地派生出多种形式的阵列和相应的估计方法,并具有较强的抗噪能力和实用性.

| Abstract: | Based on research of so called space time DOA matrix method,we propose several of its improved and generalized forms in this paper.The theoretical analysis and simulation show that,being a novel space time eigenstructure based approach for 2 D high resolution DOA estimation,the method is capable of producing a large amount of virtual elements in space time domain by space time processing.Therefore the constraint over the array configuration can be significantly weakened,and many array forms and corresponding estimation approaches,which perform better noise suppression ability and more feasibility,can be flexibly generalized. |
