DOA estimation in correlated noise fields using unitary spatio-temporal correlation matrices
Jin He · Systems engineering and electronics · 2005
The performance of traditional DOA estimation methods becomes worse in the correlated noise fields. A UST-MUSIC algorithm based on unitary spatio-temporal correlation matrices is presented. Comparison between the presented algorithm and the typical existing methods, i.e., IU-MUSIC and MMUSIC algorithms is performed. The experimental results indicate that the performance of the presented UST-MUSIC algorithm is better than that of IU-MUSIC and MMUSIC, and has good robustness to array errors and small snapshots.
