摘要
船舶水下辐射噪声场具有复杂的空间强度分布，且受到测量水域环境因素的严重影响，只有采取正确的测量方案与数据处理方法，才能获得可信结果。文中根据我国国情，提出了在浅海水域进行船舶水下辐射近场的机动检测方案，分析了水域环境参数对测量结果的影响，讨论了可能的实验设备配置及数据处理中应注意的问题，结合指出某些简易测量与分析方法的不足。
Underwater radiated noise field of a ship possesses complex spatial intensity distribution, and also greatly influenced by environmental factors of the region for measurement.Reliable results can be obtained only by proper method for measurement and data processing. In this paper a mobile system for ship radiated noise measurement in shollow water is suggested, which is more compatible for our nation, and the influence of environmental factors on measuring results is discussed. Totality of necessary measuring equipments and reasonable method of data processing are also presented. Besides, some defects in the common used simple method of measurement and data processing are pointed out.
