| 摘 要： | 本文给出声呐航行自噪声与环境噪声的模型，对半实物仿真航行自噪声与环境噪声的方案进行了分析与论证，讨论了各向同性噪声场与非各向同性噪声场的空间相关性并提出了利用球冠阵和环形阵仿真生成各向同性噪声场与非各向同性噪声场的方法。该仿真方案对于评价自导系统的静态或动态性能具有重要价值。

| Abstract: | This paper introduces the models of self-noise and ambient-noise of sonar. Using models, the project of self-noise filed and ambient-noise filed simulation in hardware-in-the-loop simulation are analyzed. The spatial correlations of isotropic and non-isotropic noise fields are discussed, and their simulation methods with circular array and spherical array are presented. These methods have a significant worthiness in evaluating the static and dynamic performance of sonar system. |
