Abstract
The detection performance of the towed linear array sonar is influenced seriously by the tow ship noise.The effects of formation ship noise upon DOA estimation of towed linear array sonar when it adopts classical beamforming method. Minimum Variance Distortionless Response (MVDR) beamforming method and blind source separation combined with MVDR method are compared systemically by the simulation data.The results show that the effects are very serious on the classical method and MVDR method.It is pre-requisite to resist the formation ship noise.But the blind source separation combined with MVDR method is superior to the classical and MVDR method, and it resists the effects of the formation ship noise to a certain extent.关键词
