| 摘 要： | 拖船辐射噪声是影响拖曳线列阵声纳探测性能的重要因素。就编队舰船辐射噪声对各自拖曳线列阵声纳采用常规波束形成方法、最小方差无失真响应（Minimum Variance Distortionless Response，MVDR）波束形成方法和盲源分离与MVDR波束形成融合方法时方位估计性能的影响，进行了全面的仿真比较。结果表明，编队舰船噪声对常规波束形成方法、MVDR波束形成方法的影响非常严重，必须采取措施对其进行抑制;而盲源分离与MVDR融合方法则表现出了优越的性能，一定程度上抑制了编队舰船噪声对拖曳线列阵声纳方位估计的影响。

| 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 ... |
