摘要： A target is provided with an acoustic chamber (4) inside which internal microphones (5) are used to receive the sound waves generated by a projectile (6) fired against the target. Internal microphones (5) are connected to a member for determining the position of impact of the projectile on the basis of the differences in transit time of sound waves jusqu'auxdits microphones (5). An outer microphone (9) is placed in front of the target, substantially in the frontal plane of the latter, to receive the sound waves generated by a projectile (6) fired against the target with supersonic velocity. The outer microphone (9) is connected to a member to determine the supersonic velocity of the projectile fired against the target based on the hit position of the projectile and transit time of sound waves to the outer microphone.
