摘　　要：在近程探测条件下,舰船应被视为体积声源,沿舰船艏艉方向分布有三个明显的声辐射亮点部位[1],即螺旋桨部位,主机部位和辅机部位,这就是舰船的三亮点模型。结合舰船三亮点模型,建立舰船通过特性的数学模型,并对实测数据作了通过特性仿真。For passive acoustic detection at a short distance, a ship should be considered as a volume sound source, there are three highlight sound-radiated positions along the fore-and-aft direction of the ships, propeller, propulsion machinery and auxiliary machineries. Based on the three-highlight model, this paper proposes a mathematical model of ship passing charactive and successively simulates a real-detected ship noise.
