摘要

在时－空二维信号模型下，基于最大似然（ＭＬ）参数估计，本文提出和归纳出三种波达方向估计方法为：①常规空域处理（传统ＭＬ方法）；②时－空域联合处理；③时－空域级联处理．文中对这些算法进行了性能分析，并对理论分析结果进行了计算机数值分析和仿真实验，最后给出了一些有意义的结论．

Abstract

In this paper

from the view point of Maximum Likelihood （ML） estimation

wepresent and classify the DOA estimation methods for signals based on 2-dimension spatial-temporalmodel as. ①spatial-only procesing ； ②temporal-spatial joint processing ； and ③temporal-spatial sequential processing. We also derive these methods’ theoritical performance. Finally

some numericalstudy and computer simulation are presented

and useful results are given.
