Research of ship radiating noise data quality evaluation system

摘要:

受到声源特性和传播信道的影响，军用舰船采集的舰船辐射噪声数据质量良莠不齐，如何标准高效可靠地评估数据质量的优劣，成为亟待解决的问题。针对这一问题，本文对舰船辐射噪声数据质量评估体系进行研究，基于舰船辐射噪声数据的组成，确定了客观评估要素，选取了要素评估指标，构建了层次化的舰船辐射噪声数据质量评估体系，搭建了舰船辐射噪声数据质量评估系统。数据测试结果表明，评估系统可实现对舰船辐射噪声数据质量的量化评估，达到对数据进行自动筛选分类的效果，对于水声数据整编、目标识别研究工作具有重要意义。

Abstract:

Affected by source characteristics and propagation channels, the quality of ship-radiated noise data collected by military vessels varies significantly. How to standardize, efficiently, and reliably assess the quality of such data has become an urgent problem to be solved. To address this issue, this paper investigates a ship-radiated noise data quality evaluation system. Based on the composition of ship-radiated noise data, objective evaluation factors are identified, key evaluation metrics are selected, and a hierarchical data quality evaluation framework is constructed. Furthermore, a ship-radiated noise data quality evaluation system is developed. Test results demonstrate that the system enables quantitative assessment of ship-radiated noise data quality and achieves automatic data filtering and classification. This work holds significant value for underwater acoustic data compilation and target recognition research.
