在自由飞行的气球上安装的次声麦克风所受的风噪很小,可以跨越地面站覆盖不足的区域,还可以捕捉到很少到达地球表面的信号。尽管这项技术很有前途,但直到最近,对气球声传感器的研究还很少。我们总结了20世纪40年代末至2014年自由飞行次声站的历史,并报告了2014 - 2016年一系列研究的结果。其中包括半个世纪以来首次在平流层记录次声的努力,一个在地面上并不总是可见的持续存在的海洋微气压峰值,以及对遥远地面爆炸的探测。我们讨论了在自由飞行的气球上部署次声传感器的独特操作方面,在高度检测到的信号类型,以及传感器响应随高度的变化。最后,我们概述了自由飞行次声传感系统的应用,包括条约验证、火流星探测、高层大气监测和金星的地震声探测。
Infrasound microphones on free flying balloons experience very little wind noise, can cross regions that lack ground station coverage, and may capture signals that seldom reach the Earth’s surface. Despite the promise of this technique, until recently very few studies had been performed on balloon-borne acoustic sensors. We summarize the history of free flying infrasound stations from the late 1940s to 2014 and report on results from a series of studies spanning 2014–2016. These include the first efforts to record infrasound in the stratosphere in half a century, the presence of a persistent ocean microbarom peak that is not always visible on the ground, and the detection of distant ground explosions. We discuss the unique operational aspects of deploying infrasound sensors on free flying balloons, the types of signals detected at altitude, and the changes to sensor response with height. Finally, we outline the applications of free flying infrasound sensing systems, including treaty verification, bolide detection, upper atmosphere monitoring, and seismoacoustic exploration of the planet Venus.
