【摘要】 海洋垂直缆水听器将声信号转换为电信号,是整个地震采集系统的核心,直接决定了垂直缆系统的灵敏度、频率特性等指标。文章从频率响应、灵敏度、本底噪声水平、功耗、满刻度这几个方面对比分析SH测试型水听器和法国Sercel MicrOBS所搭载的HTI水听器(型号HTI-94-SSQ),数据显示了SH型水听器相较于HTI水听器存在的优势和不足。更多还原

【Abstract】 The marine vertical cable hydrophone converts acoustic signal to electrical signal, which is the core of the whole seismic acquisition system, and directly determines the sensitivity and frequency characteristics of vertical cable system. This paper compares and analyzes the SH test hydrophone and HTI hydrophone(model HTI-94-SSQ)carried by Sercel Micr OBS, France in terms of frequency response, sensitivity, background noise level, power consumption and full scale. The data show the advantages and disadvantages of SH hydrophone compared with HTI hydrophone.更多还原
