地震信号检测是进行各种地震数据分析和处理的首要任务,STA/LTA方法具有算法简单、便于实时处理等特点，被广泛应用于地震信号检测中，但是利用该方法进行近震信号检测时，不同的设置参数对地震触发的效率不同。本文结合实际震例数据研究了STA/LTA方法进行地震信号检测的各种影响因素，得到STA/LTA方法进行地震信号检测时最合理的参数设置范围，为区域测震台网的地震信号检测参数设置工作提供参考。
Seismic signal detection is the main task of different seismic data analysis and process. Because STA/LTA method has the features of simple algorithm and real-time processing,so it’s widely used in the seismic signal detection. The appliance of this method to signal detection of local earthquake events, has different effects of seismic trigger, which is influenced by different parameters. This article studys the Influencing factors of seismic signal detection using STA/LTA method with actual earthquake events, and the most reasonable parameters of seismic signal detection are given, also providing a reference for seismic signal detection parameters setting of regional seismic network.
