摘要翻译：
提出了一种基于流体动力学模型COCOS模型的多通道人工风噪声发生器。特别地，该模型被用来逼近在自由场中用紧密间隔的传声器测量的风噪声信号的复相干函数，并用于时不变的风向和风速。初步实验集中在记录的风噪声信号的空间分析和不同测量设置的Corcos模型的验证。然后，利用COCOS模型综合生成具有所需复相干性的风噪声信号。设计了多通道信号发生器，扩展了现有的单通道信号发生器，以产生N个相互不相关的信号，同时利用一种在复相干约束下产生多通道非平稳噪声信号的算法，得到了预定义的复相干函数。合成信号的时间、频谱和空间特征与实测风噪声的观测结果相吻合。人工生成克服了收集纯风噪声样本进行降噪评估的耗时挑战，并在模拟中使用的生成信号数量上提供了灵活性。

英文摘要：
  A novel multi-channel artificial wind noise generator based on a fluid dynamics model, namely the Corcos model, is proposed. In particular, the model is used to approximate the complex coherence function of wind noise signals measured with closely-spaced microphones in the free-field and for time-invariant wind stream direction and speed. Preliminary experiments focus on a spatial analysis of recorded wind noise signals and the validation of the Corcos model for diverse measurement set-ups. Subsequently, the Corcos model is used to synthetically generate wind noise signals exhibiting the desired complex coherence. The multi-channel generator is designed extending an existing single-channel generator to create N mutually uncorrelated signals, while the predefined complex coherence function is obtained exploiting an algorithm developed to generate multi-channel non-stationary noise signals under a complex coherence constraint. Temporal, spectral and spatial characteristics of synthetic signals match with those observed in measured wind noise. The artificial generation overcomes the time-consuming challenge of collecting pure wind noise samples for noise reduction evaluations and provides flexibility in the number of generated signals used in the simulations.
