The Effect of Snapshots on Toeplitz Music Algorithm with MRA

Under the situation of minimum-redundancy array (MRA), snapshot will impact on the estimation performance of the direction of arrival (DOA). In respect of Toeplitz multiple signal classification (MUSIC) algorithm´s principle, this paper has analyzed the correlation coefficient to the Toeplitz MUSIC algorithm influence, and through deducing the relation between snapshot and correlation coefficient, we conclude the snapshot, sampling time, sampling rate´s influence to the Toeplita MUSIC algorithm indirectly. Finally we validate the conclusion through simulation experiments.
