简介：拖引的站台噪音的干扰特征源于推进器并且拖引身体因为活跃/被动的拖引的数组被分析。在浅水环境，反映的直接波浪和底部/海表面飘动，这被显示出将严重影响声纳系统的性能。为以各种各样的参数计算干扰的到达(DOA)的方向的公式例如数组深度，一些拖引电缆线，是干扰噪音的derived.The效果因为声纳系统的察觉性能是系统模拟的described.The结果为减少这些种干扰的效果提供方法。

简介：在坚硬地在任意的角度连接的二个无限的盘子的角落接口的颤动精力传播被波浪途径学习以便调查堵住使用减少把波浪传播弄弯的飞机的质量的效果。二个本地坐标系统被介绍，暗示管理盘子的典型阻抗或堵住质量的相应比率的六个新非维的系数被介绍简化传播和思考系数的明确的表达。五件样品在experiment.Discussions被测试以插入损失基于在预言和实验之间的比较被执行。在角落接口堵住质量象“一个lowpass过滤器”一样行动，这被结束，为在某些频率上面的颤动变细有效。在“变细乐队”的TL和IL的价值每每统一一些堵住的团在惯性的集体时刻统一“变细乐队”的长度和乐队宽度主要取决于质量。
