摘要

本文讨论在时－空二维信号模型下信号波达方向估计问题．本文首先对时－空二维信号模型进行了描述，然后分析了在该模型了信号时域信息不能利用、时域信息可以利用以及时域信息完全已知等情形时波达方向估计的克拉美·罗界（ＣＲＢ），并讨论了这几种ＣＲＢ之间的关系，最后给出了几点主要结论．

Abstract

This paper deals with the estimation of DOAs for signals with Temporal-Spatial2-Dimension model. Following the description of the T-S 2-D data model

the CRBs of DOA estimation of signals with this data model are analyzed in the cases that the signals’ temporal information is not utilizable

the signals’ temproal information is utilizable and the signals’ temporal information are entirely known. The relationship between these CRBs is also discussed. In the end ofthis paper

some main results are given.
