摘要
覆盖消声瓦是水下目标隐身的一个主要方法 ,对敷瓦消声效果的预报是敷瓦工程的一个重要环节。预报的关键是对消声瓦吸声效果的数值分析和目标回波强度的计算方法。本文分析了消声瓦的吸声机理 ,据此 ,采用传递矩阵法和参数匹配方法求得敷瓦多层结构在任意方向的反射系数 ,再通过物理声学方法计算目标回波强度 ,给出预报值 。
It's a useful method to cover an underwater target with silent tiles for silence. Therefore the predict of anechoic effect is important. In this paper, the absorbed mechanism of the silent tile is analyzed, the transmission matrix method and parameter matching method are used to compute reflecting coefficient of multiple layer structure by covered the silent tile in any direction. At last, we get the values of target strength(TS) and compare them with experimental results.
