地震信号的数据格式转换

The data format converting of the seismic signal

常规分布式地震数据采集系统从检波器输出模拟地震信号开始,到地震数据记录在磁带记录介质结束,地震数据要经过模拟信号放大、滤波、AD转换、DSP处理、数字传输、相关/叠加和噪声编辑等过程。在不同的环节,其数据格式将表现出不同的形式。文章介绍了目前具有代表性的法国SERCEL公司408UL/XL地震数据采集系统在进行数据采集、处理和记录过程中的各种数据格式的转换,供相关人员参考。

For distributed seismic acquisition system,seismic signal are transmitted via pre-amplifier,filter,ADC,DSP,data process unit,and finally the seismic geophones are recorded on the tape recorder.Date appear to be different formats in different links in the transmission.The paper introduces the date formats in different links of 408UL/XL system,witch gives a reference to our colleagues.
