| 中文摘要: |
| 脉冲声技术是一种很常用的水声测量技术,但由于脉冲声存在着瞬态过程,严重影响了它在低频下的使用。本文中研究的水声测量用声脉冲瞬态抑制方法,通过瞬态抑制等效消除换能器的瞬态过程,从而为在有限尺寸水域内扩展水声测量低频限创造了条件。 |
| 英文摘要: |
| Sound pulse technique is often used in the underwater acoustic measurement, but it has transients, so it can not be used in low frequencies. The sound pulse transient suppression method investigated in this paper removes the transients through the transient suppression. Consequently, the low frequency limitation of the small size tank for measurement will be expanded. |
