摘　　要：为了修正目前国内所普遍采用的船舶辐射噪声测量方法,建立了一个具有一定空间分布的船舶辐射噪声源模型。利用波数积分方法仿真计算了该模型在自由场条件下的近程声场,并分析了近场辐射噪声的基本规律。仿真结果与国外文献提供的船舶水下辐射噪声近场特性吻合,验证了所建模型的正确性。In order to modify the measuring method of warship radiated noise which has been widely used in our country, a physical model of warship radiated noise model with some spatial distribution was provided. The sound pressure at near distance under free field was computed by using the wave number integration and the basic characteristics of the radiated noise were analyzes. The simulation results are in accordance with the characteristics of the radiated noise at near distance in the foreign literature, which thus validates the physical model of warship radiated noise.
