The effect of ocean wave on the vertical spatial correlation of ocean ambient noise

The effect of the correlation function of noise sources derived from the ocean wave spectrum on the vertical spatial correlation of ocean ambient noise is investigated. The existing spatial correlation models of ocean ambient noise usually assume that the noise sources in the surface are uncorrelated. This assumption can be used to explain some physical phenomena, but it is not consistent with the real situation. Considering the relation between the ocean wave motion and the ambient noise caused by wind, the spectrum of ocean wave is introduced to calculate the vertical correlation of ocean ambient noise as the correlation function of noise sources by using the Kuperman-Ingenito(K/I) noise model. From the comparison of the simulation results and the experimental results, it is known that the simulation results of vertical correlation of ambient noise have some differences with the experimental results by assuming the noise sources are uncorrelated and the simulation results of vertical correlation of ambient noise have a good agreement with the experimental results by using the correlation function of noise sources derived from the ocean wave spectrum under the situation of high wind speed.
