| 摘 要： | 舰船辐射噪声是多年来水声学领域研究的重要对象,对其特征的监测可以发现处于亚健康状态下的舰船,对舰船的维护和保养具有重要意义.本文从宽带连续谱的角度出发,制定特征监测方案.在实现各功能模块的基础上,将其进行整体联调.运用舰船在海上的实测信号对整个方案进行验证,并在多种特征提取方法和相似度计算方法中得到最优组合.

| Abstract: | Worship radiated noise is an important study subject in the field of underwater acoustics for many years.Feature monitoring of worship radiated noise can find out the worship which is in the state of subhealth,and has an important significance in worship maintenance.Feature monitoring scheme has been established from the view of continuous spectrum in the paper.The whole scheme has been debugged,based on achieving every module.Then using the actual measurement data in the sea validates the scheme.And get th... |
