VTUAD: Vessel Type Underwater Acoustic Data

A curated dataset containing underwater acoustic signals categorized into five different classes based on the vessel type: Cargo, Tanker, Tug, Passengership, and Background. Different subsets of data were generated from the original data considering the distance from the vessel to the hydrophone picking up the vessel's sound. These subsets, or scenarios, were created considering inclusion and exclusion radii: the first scenario has an inclusion radius of 2km and an exclusion radius of 3km; the second is defined within the interval of 3km and 4km between inclusion and exclusion radius; the third scenario is defined within the interval between 4km and 6km. Also, environmental information, obtained from the CTD recorder, is available, containing five different signals: temperature, measured in Celsius; conductivity, measured in siemens per metre; pressure, in decibar; salinity, measured in psu; and sound speed, measured in meters per second. For every different instance, the average of the measures was considered.

经精心筛选整理的水下声学信号数据集，按船舶类型分为五类：货船（Cargo）、油轮（Tanker）、拖船（Tug）、客船（Passengership）以及背景噪声（Background）。本数据集基于船舶与采集其声学信号的水听器（hydrophone）之间的距离，从原始数据中生成了多组数据子集。这些数据子集（亦称场景）通过设定包含半径与排除半径生成：第一组场景的包含半径为2千米、排除半径为3千米；第二组场景的包含与排除半径区间为3千米至4千米；第三组场景的区间为4千米至6千米。此外，数据集还提供了来自温盐深记录仪（CTD recorder）的环境信息，包含五项环境参数：以摄氏度（℃）为单位的温度、以西门子每米（S/m）为单位的电导率、以分巴（dbar）为单位的压力、以实用盐度单位（psu）为单位的盐度，以及以米每秒（m/s）为单位的声速。针对每一个独立的数据实例，均采用其测量值的平均值作为统计结果。

背景概述

VTUAD数据集是一个包含五种不同类型船只水下声学信号的精选数据集，数据根据船只与接收声音的水听器之间的距离分为三个子集（2-3km, 3-4km, 4-6km），并包含环境信息如温度、电导率等。
