摘要
地震台阵的历史起始于５０ 年代末， 当时其目标主要是检测核爆炸产生的地振动信号与鉴别核爆炸信号和地震信号。我国地震学家在７０ 年代也曾对台阵作过初步研究。在台阵的发展过程中， 许多新技术被引进用于信号处理， 数据分析和解释。本文主要介绍频率扫描聚束及视速度扫描聚束在台阵数据处理中的应用， 并使用该技术在上海地震台阵选址中的具体实现。
The history ofSeism icArray wasstarting in theendof50′s,which targetswerem ain- ly to detectsignals thatare created by nuclearexplosion and to distinguish signals ofnu- clearexplosion from signalsofearthquakeatthatm oment.TheseismologistsofChina also tentatively studied Array in 70′s.In theprocessofdeveloping array,m any new techniques havebeen introduced into disposalofsignaland analysisofarray′sdata.In thispaper,the application offrequency beam form scan and apparentvelocity beam form scan in analyzing array′sdata wasintroduced and wasspecially studied, and thesem ethodswere concretely applied in selecting site ofShanghaiSeism icArray.
