Infrasound Data Analysis for Wake Vortices and Maritime Vessel Detection

Infrasonic signatures are long wave acoustic signals in the under 20Hz range (below human hearing). The partner organization has been experimenting with infrasonic sensors to achieve 2 key outcomes: a) detection clear air turbulence to benefit commercial air travel and b) detection of ‘dark vessel’ marine traffic, i.e., illegal fishing.The ability to detect clear air turbulence from the host aircraft in real time offers a savings to the airline industry (between $500M and $1B per year) in lost time accidents and costly fly arounds for suspected turbulence. “Climate modelling studies have indicated that the amount of moderate-or-greater clear-air turbulence on transatlantic flight routes in winter will increase significantly in future as the climate changes.” (1). The partner organization has an October test campaign planned with the sensor flown on a full-size jet on a transoceanic flight profile.Each of these campaigns will provide a deluge of datasets that require leading edge analysis from the candidate to understand the relationships between the infrasonic source and the sensor location, be they stationary and/or airborne.
