Characterization and modeling of wind-dominated ambient noise in South China Sea

DongGe Jiang  ZhengLin Li  JiXing Qin  ZhaoHui Peng  Hao Shao  
【摘要】:正The action of wind on the sea surface plays an important role in the noise generation mechanism.Sea surface wind speed can be estimated accurately provided there is an accurate understanding of the relationship between the ocean ambient noise and wind speed.Many measurements and analyses of the wind dependence of ambient noise have been conducted.The approximate empirical rule given by Wenz[1]states that in the frequency band between 0.5and 5 kHz,the ambient sea-noise spectrum levels decrease
