| Abstract: | Based on the space time eigenstructure of signals,a novel space time DOA matrix method is proposed to estimate the high resolution 2 D DOA of narrowband signals.The method transfers the observed data from space domain to 2 D space time domain by exploiting the cross correlation of the array outputs,and a large amount of virtual elements are generated through space time processing.Therefore the constraint over the array configuration and the element identity can be significantly weakened,which means the matching subarray is no longer needed and the advantage of the traditional DOA matrix method,such as automatical parameter alignment and no need of 2 D search,is still available.The simulation results show the effectiveness of the method. |
