摘要: 简要叙述了地震事件监测研究的历史和现状,结合远震信号的地震学特点,对远震P波群信号进行了自适应时-频分析。实验结果表明,特定台站-区域对的爆炸远震P波群的时-频分布具有极强的相似性。

关键词: 地震事件, 识别, P波群, 自适应时-频分析

Abstract: It outlines the historical and current situations of monitoring of seismic events.According to the seismology characteristics of teleseismic signals from nuclear explosion,their P wave groups are analyzed by joint time-frequency analysis.It proves that,the time-frequency distributions of the NE teleseismic signals'P wave groups are most similar to each other.

Key words: seismic event, identification, Pwave group, adaptive time-frequency representation
