| 摘 要： | 本文探讨了吸声材料的声压反射系数、吸声系数、回声降低(ER)与目标强度变化(△TS)等参数之间的解析关系。建立了敷瓦潜艇目标强度降低与声呐作用距离减小的数学表达式。按照＇当量原理＇对假想潜艇缩比模型裸体与敷瓦时的目标强度进行了测量。ER与△TS的实测值一致性很好。

| Abstract: | This paper gives mathematic relations of parameters between pressure reflaction coefficient, absorption coefficient, echo reduction and target strength. We has been buit the mathematical relationship in target strength reduction of tiling for submarine and reducing range of sonar.We also separately measured target strength of nude and tiling submarine for an imaginary reduced scales on the principle of similar equivlent proportions. It has been found that EE and measuring ATS are consistent. |
