摘要 相对于大多数声呐，海洋环境噪声通常被视为背景干扰。水听器基阵的信噪比增益成为了基阵设计和
性能估计的重要参数。从空间相关特性的角度看，当信号场已知时，阵增益可唯一由噪声场的空间相关特性来
确定，这就是海洋环境噪声空间相关特性建模的动机。根据环境和声场之不同，文献中已给出几种不同的噪声
场模型。为了阐明已有模型的特点及未来的研究方向，该文对噪声场空间相关特性建模做了简要综述。

Abstract Ocean ambient noise is usually considered to be the background interference for most of sonar
systems. Thus the quantity signal-to-noise ratio (SNR) gain becomes the key parameter for the design and
performance estimation of a hydrophone array, which is usually called array gain. From the point of view of
spatial correlation array gain can be only determined by the spatial property of the interference field when
the knowledge of the expected acoustic field is given. This is the motivation for ocean ambient noise modeling
and several models for the calculation of correlation coefficients were presented in the literatures corresponding
to different environments and noise fields. In order to clarify the characteristics of those given models and
demonstrate the research directions of ocean ambient noise in the future, some reviews of correlation modeling
were presented in this paper.
