Abstract [en]

Shooter localization in a wireless network of geographically distributed microphones is studied. The arrival time of both the acoustic muzzle blast (MB) from the gunfire and the ballistic shock wave (SW) from the bullet can be registered by the microphone nodes and considered as measurements. To relax the requirements on accurate node clocks, the approach to base the localization on the time difference of MB and SW at each sensor is analyzed. Cramér-Rao lower bound analysis indicates how a lower bound of the root mean square error depends on the synchronization error for different approaches to use the measurements. The localization problem is formulated in a separable nonlinear least squares framework. A simplified ballistic model with only one, assumed unknown, parameter is used. Results from field trials with different types of ammunition demonstrate excellent results using the MB-SW difference for both the position and the aiming angle of the shooter.
