Field Experiments on Shooter State Estimation Accuracy Based on Incomplete Acoustic Measurements
Luisa Still, Marc Oispuu · 2020
This paper investigates the problem of shooter localization fusing complete or incomplete experimental data of one or multiple acoustic sensors. A microphone array can measure a complete measurement data set, composed of two bearing angles of the two impulsive sound events of a supersonic bullet and the TDOA between both events, or an incomplete subset. In this paper experimental results from a field experiment with volumetric microphone arrays are investigated and compared with the associated Cramér-Rao bound.
