Leveraging Infrasound Signals for Integration of Ground- and Space-Based Nuclear Explosion Monitoring Capabilities
Description:
Nuclear detonation detection is typically conducted via analysis of a combination of phenomenologies including seismic, infrasonic, hydroacoustic, air sampling, and satellite-based observations (e.g., light, gamma ray, x-ray, neutron). The ground-based components of such monitoring systems are ideal for detecting and characterizing below-ground and near-surface explosions while space-borne sensors can reliably detect and characterize nuclear explosions in the atmosphere. Recent research at Los Alamos National Laboratory has focused on developing and improving physical and statistical frameworks to better integrate and communicate information between these individual phenomenologies for near-surface and atmospheric nuclear explosions. Specifically, infrasound source models for supersonic sources in the atmosphere have been developed and evaluated to distinguish infrasonic signatures from such sources compared with point source explosion sources. Ray-based weakly non-linear waveform analysis has been utilized to construct infrasonic detection statistics and investigate coupling of infrasonic energy in the immediate footprint of the airburst to the seismic surface wave field. These and other aspects of this ongoing effort to integrate ground- and space-based nuclear explosion monitoring capabilities will be presented.
