摘要
鉴于射线模型明确的物理意义及海洋锋特殊的海洋环境现象,文章运用三维射线模型研究了声波在海洋锋区的传播规律,并通过仿真试验,讨论了台湾黑潮锋区的三维声线轨迹的特点及其对声呐探测带来的影响。研究的结果表明,声波在通过海洋锋区时,一般都将产生较大的垂直深度误差和水平方位误差,特别是在台湾以东的黑潮锋区,影响比较明显。
Based on the physical meaning of the ray model and the special environment of the ocean front regions, this paper uses a three-dimensional ray model to study sound propagation in these regions. Through simulation the paper also discusses the characteristics of 3D ray tracing in Taiwan Kuroshio region and their effects on sonar detection. The results show that rays in the front regions always have relatively large vertical depth errors and horizontal azimuth errors, particularly in the Kuroshio region.
