声纳方程的瞬态形式讨论

Discussions on the transient-state sonar equation

本文提出用瞬态信号的能谱级代替稳态信号的声强级来定义声纳参数,并以短柱声散射为例,运用数值模拟方法,验证用能谱级定义声纳参数,声纳方程是比较有效的,这为应用声纳方程处理瞬态声信号从而获得目标的目标强度提供了一种有效可行的方法。

This article suggests defining the sonar parameters by the energy spectrum levels of the transient signals instead of the strength levels of the steady-state signals, On taking the sound scattering of a short cylinder as an illustration, it proves that the sonar equation is still effective. This paper thus provides an effective method to treat the use of a transient signal to obtain the target's scattering character.
