核爆次声背景噪声信号特征分析

Analysis of the Characteristics of the Background Noise from a Nuclear Explosion Monitoring

核爆炸次声监测技术是《全面禁止核试验条约》规定的监测技术手段之一,主要用来监测大气层中的核爆炸。根据核爆次声监测对背景噪声信号影响的关注,重点介绍了地震、火山喷发、闪电、大风等非核爆次声信号的特征,了解这些特征对于开展核爆次声监测有益。

Infrasound monitoring is one of the four monitoring technologies stipulated in ＂ The Comprehensive Nuclear - Test - Ban Treaty＂. According to the interest in the understanding of background noise during nucle- ar explosion infrasound monitoring, the discussion is concentrated on the infrasound caused by earthquake, vol- canic eruption, lightning, gale and so on. It＇s very important to understand these characteristics for developing nuclear explosion infrasound monitoring.
