摘　　要：为提高复杂环境下低频宽带自导系统的整体性能,针对鱼雷自导系统的自噪声特性,建立了鱼雷自导系统自噪声技术体系,分别对电子装置电噪声、声学装置磁辐射噪声、热噪声、流噪声和结构振动噪声进行了研究。开展了高阻尼基阵壳体和声学基阵的隔振材料及结构设计研究,分析了流噪声对自导系统接收性能的影响。最后,针对鱼雷自导系统减振降噪方面存在的问题给出了解决途径。文中的研究可为低噪声鱼雷自导系统设计提供参考。To improve the overall performance of low-frequency broadband homing system in complex environment, a self-noise technology system of torpedo homing system is established considering the self-noise characteristic of torpedo homing system. The electronic equipment noise, acoustic device magnetic radiation noise, thermal noise, flow noise and structure vibration noise are investigated. The vibration isolation materials and structure designs of high-damping array shell and acoustic array are studied. The influence of flow noise on homing reception performance of torpedo homing system is analyzed. In addition, countermeasures against the vibration and noise reduction of torpedo homing system are offered. This research may provide a reference for design of torpedo homing system with low noise level.
