Major Accomplishments

• NCPA infrasound research previously funded by Congress transitioned to U.S. Army SMDC annual budget.
• Continued the development of the outdoor sound propagation research site at Locke Station and performed several successful propagation experiments at the site.
• Continued the development of very promising new signal processing algorithm that couples previously developed phase fluctuation processing with Hilbert transforms.
• Continued the study of the microbarom signal in an ocean of finite depth.
• NCPA led the research effort for the US Army Space and Missile Defense Command Advanced Acoustic Sensor Technology Research (ASTER) program. This effort involved 13 subcontractors in a wide spectrum of infrasound research including propagation modeling, advanced sensor development, development of sensor calibration standards and facilities, and collection and analysis of infrasound data from explosions, bolides, hurricanes, and volcanoes.
• NCPA provided management oversight for US infrasound and seismic sensor stations for the Comprehensive Test Ban Treaty Organization International Monitoring System.
