Study of the high resolution DOA estimation technology based on the beam space MUSIC algorithm

Modern sonar systems generally use hydrophone arrays and advanced signal processing techniques to improve their detection and localization abilities,and beam forming plays an important role.Narrowband beam space high resolution bearing estimation techniques are studied in this paper.The construction procedure and performance of beam space MUSIC algorithm are analyzed for the weak correlated signals.Computer simulation results show that the beam space MUSIC algorithm has its super performance.
