Systems and methods for disambiguating shooter locations

摘要

A system for extracting a signal from a muzzle wave in the presence of a shockwave signal, comprises an array of spaced acoustic sensors forming an antenna for measuring at least an initial portion of the shockwave signal. A time window having a width corresponding to a time required for a muzzle wave to traverse the sensor array is defined. Responsive to detection of the shockwave signal, the window is advanced and total energy received in the window as a function of time is measured. A maximum of the measured total energy is associated with the muzzle signal.
