摘要

In this study the importance of wind for acoustic gunshot localization, i.e. its influence on the accuracy of the direction of arrival, is studied. A correction factor is applied to account for the influence of wind on sound propagation. The final objective of this work is to locate marksmen using acoustic vector sensors (AVS) instead of arrays of conventional microphones. To allow for comparison with these AVS, experiments were performed, in which the direction of the sound source was evaluated using two microphones. By estimating the time difference of arrival and by cross-correlating both channels, it is possible to compute the source direction. The direction of arrival estimation was accurate to 1.9 degrees at wind speeds below 2 m/s. These measurements can serve as a baseline for accuracy tests with AVS.
