用相关分析法检测两种地震计性能及记录数据差异
|
摘要
阐明利用同点记录数据相关性检测两种地震计性能及记录数据差异的方法,并用两台经过测试且性能相同的FBS-3B型地震计进行验证,最后用该方法检测了STS-2、KS-2000型地震计的高频段性能及记录数据差异。
The Cross-correlation method for checking two types of seismometers' performance and recording differences is clarified through two series of data at the same site at Kunming station.And this method is demonstrated by an example of two FBS-3B seismometers whose performances are similar.Then the method is applied to checking the performance of STS-2 and KS-2000 wide-band seismometers in high-frequency band and the difference between the recordings of these two kinds of seismometers.
