| 摘要 | A device determines velocity of a bullet. The device includes two electro-acoustic sensors arranged with a predetermined distance for determining velocity of a bullet. Each of the electro-acoustic sensors are configured to detect acoustic energy of a shock wave generated by the bullet travelling at supersonic speed from a point of fire to a target and configured to transduce the acoustic energy into an electrical signal. The device includes a processing unit configured to receive electrical signals from the electro-acoustic sensors as the bullet travels and to determine a time frame between the two second electrical signals. The velocity of the bullet can be determined based on the time frame. The device also includes a sighting unit attached to a housing of the device for aligning the electro-acoustic sensors parallel to the direction from the point of fire to the target. | ||||||
