Systems and methods for tracking impacts |
摘要 |
Surface impacts are located and characterized based on an acoustic signal produced by the impact despite the presence of signal dispersion. Acoustic signals from the surface may be compared to acoustic signals detected external to the surface in order to eliminate spurious impact sensing due to external sounds. Low-frequency acoustic signals may be sensed and identified as explicit hard "bangs" which are of limited utility for pointing and tracking applications.
