摘要
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。结合实际震例数据研究STA/LTA方法进行地震信号检测的各种影响因素,得到该方法进行检测时最合理的参数设置范围。
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 application of this method to signal detection of local earthquake events has different effects of seismic trigger, which is influenced by different parameters. In this article, the influencing factors of seismic signal detection u sing STA/LTA method with actual earthquake events are studied, and the most reasonable parameters of seismic signal detection are given. The results provide a reference for parameter setting of seismic signal detection in regional seismic network.
