摘　　要：为了研究采用波束形成技术监测本艇辐射噪声技术中拖曳线列阵阵位预报问题,定义了拖曳线列阵阵位与潜艇之间的相互几何关系,采用舰艇拖曳系统耦合动力学模型,仿真预报了潜艇U形机动和操舵定常回转运动时的拖曳线列阵阵位,得到了潜艇航速、操舵角度、拖缆长度变化与阵位的相互关系,依据预报结果确定了用波束形成技术监测本艇辐射噪声所应采取的操艇模式及拖曳线列阵布放参数.研究表明,采用定常回转机动可以获得满足本艇辐射噪声监测要求的稳定的拖曳线列阵阵位,拖缆长度和回转舵角对拖曳线列阵阵位影响较大,回转速度对拖曳线列阵阵位影响较小.In order to predict the position of a towed array actively measuring a submarine＇s self generated-noise by the beamform technique, geometrical relationships between the towed array and the submarine were defined. Using a coupling dynamical model for a warship＇s towed cable-array system, the authors predicted the array＇s position relative to the submarine and the lineup of the towed-array during U-shaped and circular maneuvers. From this, the relationships between the towed-array＇s position and the submarine＇s velocity, rudder angle and cable length were predicted. The research indicates that, when maneuvering in circles, a steady position of the towed array can be maintained, and that rudder angle and cable length have great influence on the position of the towed array while the submarine＇s velocity has little influence.
