摘要
本文介绍了一种宽带参量发射阵。利用匹配层技术,设计制作了一个40路的小尺寸,大功率,宽频带,高指向性参量阵。换能器中心频率为100 k Hz,峰值响应为184.9 d B,带宽40 k Hz,与仿真结果基本一致。该换能器阵能应用于水下掩埋物的探测、水下通信以及港口警戒。
In this paper, a broadband parametric acoustic array is introduced. Using the matching layer technique, the author designed and manufacture a small size, high power, broadband, high directivity of 36 way parametric acoustic array. The array has maximum transmitting voltage response of 184.9 d B,it has bandwidth of 40 k Hz. The measured results are basically accordant to simulated results. This array can be used for the detection of underwater buried objects or underwater communication, it also can be used for port defense.
