摘要
通过对英山数字地震台台址背景噪声的分析和计算,得出了台址背景噪声地脉动速度均方根(RMS)值、观测动态范围和噪声信号功率谱,表明台址地脉动噪声水平基本符合数字地震观测技术规范要求。
The task for selection and construction of Yingshan digital seismostation comes from sub-programs of Hubei Provincial earthquake background field exploration project,which is one of newly-built unattended digital seismic stations in Hubei province during the Eleventh Five-Year period.By analyzing and calculating the background noise of Yingshan digital seismostation,we got the root-mean-square(RMS) value of the ground pulsation speed,the dynamic range of observation and the power spectrum of the noise signal about the background noise of station.The result shows that the background noise level of the station satisfy basically the normative requirement of the digital seismic observation technique.
