摘要
舰船声特征信号的预测和评价是当前国内外的前沿课题,也是迫切需要发展的研究领域。迄今推广运用了国外的三种软件:辐射噪声估算软件——NDES、声目标强度估算软件——ARTES、综合辐射噪声与自噪声建模软件——FNVNOISE。以上方法将声特征信号预测建立在理论计算基础上,对于复杂问题均建立了各种专门用来帮助设计人员进行重要计算的数据库。研究人员可通过不断增加和核对新的数据,使数据库和计算方法得到不断改进和完善,从而为将来在解决设计中遇到的问题提供更有效的支持。
Prediction and evaluation of acoustic signature on ships is a frontier subject and a field to be developed. Three kinds of popular software, radiation noise evaluation software-NDES, target strength evaluation software-ARTES, and integrated radiation noise and self-noise modeling software-FNVNOISE, were introduced in the aspects of principles, utility and functions. By means of above software, prediction of the acoustic signals was completed based on theoretical calculation. The computation output was used to establish a database which can help designers for essential calculations of complicated issues. The database and algorithm can be constantly improved and updated through addition and verification of new data in order to provide solutions for new problems in future design.
