Detection of Atmospheric Explosions at IMS Monitoring Stations using Infrasound Techniques

Abstract

Work is continuing on the development of infrasound techniques that can be used to improve detection, location and discrimination capability for atmospheric nuclear explosions at International Monitoring System (IMS) infrasound monitoring stations. In particular, we are continuing to focus on the detection of atmospheric explosions in the distance range from about 500 to 4500 km. We note that good detection capability in this distance range is essential to ensure that the global IMS infrasound network has acceptable monitoring capability, including good capability for the detection of explosions that occur over the vast open ocean areas in the Pacific, Indian and Southern Oceans. This investigation has therefore been primarily concerned with a detailed study of the properties of infrasound generated by regional and distant atmospheric explosions and the development of techniques that can improve detection capability for regional and distant sources at infrasonic monitoring stations.
