Geolocating sources of acoustic signals with a balloon-borne aeroseismometer
| Abstract: Various embodiments described herein provide for a balloon-borne aeroseismometer that can detect infrasonic signals and concurrent vibrations caused by the infrasonic signals. Through a set of motion sensors that can detect acceleration in three planes, the aeroseismometer can determine the direction of vibration and thus determine a travel path of the infrasonic signal relative to the aeroseismometer. The aeroseismometer can also translate the direction of the source from a reference frame of the aeroseismometer to an external reference frame, such as a planetary coordinate system, in order to identify potential locations of a source of the infrasonic signals. |
