摘要: The acoustic detection antenna (5) has a number of microphones (6) at equally spaced intervals, with the spacing in region 10 s centimetres. detect sound signals emitted as bullet (4) is fired from gun (3). Sound signal magnitudes and their time separation are measured real time. Two detected, first intense supersonic speed, second gun. Processing information allows firearm position to be found.
