中国数字地震台网数字化地震数据的仿真处理

THE SIMULATION PROCESSING OF CDSN DIGITAL SEISMIC DATA

对中国数字地震台网记录的宽带数字化地震数据进行了仿真处理，即将记录映射成多种传统窄带地震仪（ＳＫ，ＤＫ１，ＤＤ２和７６３等）的记录，并通过与实际记录的比较联合解释了模拟记录和仿真数字记录．分析结果证实了仿真技术在数字化地震数据处理中的有效性和可行性，从而为仿真技术的进一步应用提供了依据．

In this paper,the simulation processing of CDSN digital seismic data is introduced.The CDSN digital recordings are converted into many narrow band recording modes such as SK,DK 1,DD 2,763, etc..The analogous and digital recordings are interpreted by comparing converted recordings with original recordings.The result shows that the simulation processing is effective and useful in the digital seismic data processing.
