全面禁止核试验条约组织(The Comprehensive Nuclear-test-ban Treaty Orginization,CTBTO)筹委会临时技术秘书处(Provisional Technical Secretariat,PTS)国际数据中心(International Data Centre,IDC)负责对来自国际监测系统(International Monitoring System,IMS)台站数据的接收、处理、分析、报告及归档.降低在全球范围内的监测阈值,提高自动处理结果的准确性,是IDC一直以来所追求的目标.在核查地震监测方面,IDC不断改进数据处理软件以满足监测技术发展所带来的新需求,开展了软件结构优化、精确的地球物理模型应用,先进的数据处理方法集成等工作.本文首先简要介绍了IDC地震数据处理方法,然后从软件结构、信号检测与关联算法、区域走时模型等几个方面总结了目前IDC地震数据处理软件研究进展,对涉及的相关算法进行了分析.希望对国家数据中心数据处理软件的发展、以及对核查技术相关的研究工作起到借鉴作用.
The Comprehensive Nuclear-test-ban Treaty Orginization (CTBTO) Preparatory Committee Provisional Technical Secretariat (PTS) The International Data Center (IDC) is responsible for providing information from the International Monitoring System International Monitoring System (IMS)) Receiving, processing, analyzing, reporting and archiving of station data Reducing the global monitoring threshold and improving the accuracy of automated processing results have been IDC’s long sought after goal. In the aspect of IDC, data processing software is continuously improved to meet the new demands brought by the development of monitoring technology, and software optimization, precise application of geophysical models and integration of advanced data processing methods are carried out.In this paper, IDC seismic data Then summarizes the current research progress of IDC seismic data processing software from the aspects of software structure, signal detection and correlation algorithm, regional traveltime model and so on, and analyzes the relevant algorithms involved.I hope to analyze the data processing software of National Data Center Development, and research related to verification technology Work serves as reference.
