摘要
文章介绍了利用软件平台,开发出采用经典谱估计中算法的背景噪声计算程序的设计原理及实际应用。该程序的应用,解决了天津测震台网各台站背景噪声的统一计算、批量成图等问题,从而实现了对数字地震台网数据记录质量、背景噪声变化的监控以及各频段噪声特性的对比分析,提高了天津台网背景噪声计算的工作效率。
The program of background noise calculation using the algorithm of classical spectral estimation is developed on Matlab software platform.Design principle and application of the program are introduced in this paper.The application of the program solves the problems of background noise calculation of each station in Tianjin Seismic Network and mapping in batches and can monitor the data record quality,change of background noise and analyze noise character of each frequency band comparatively.So work efficiency of background noise calculation in Tianjin Seismic Network is improved.
