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
