US12523447 - Device, method and vehicle
The patent describes a device that determines the firing position of a projectile by utilizing both impact and acoustic sensors to detect the projectile’s impact and muzzle blast. The determination unit processes these signals, including a pressure wave from the projectile, to accurately identify the origin of the shot.
Claim 1
1 . A device for determining a firing position from which a projectile has been fired at a target object, comprising: an impact sensor unit for detecting an impact of the projectile in the target object; an acoustic sensor unit for detecting a muzzle blast when the projectile is fired; and a determination unit for determining the firing position on the basis of the detected muzzle blast and the detected impact, wherein the impact sensor unit comprises a structure-borne sound detector for detecting the impact of the projectile, a sensitivity of the impact sensor unit is configured to detect the impact of the projectile fired from a weapon having a caliber equal to or greater than 5 mm, the projectile having a kinetic energy of 50 joules or more, the acoustic sensor unit additionally detects a pressure wave of the projectile when the projectile passes the impact sensor unit, and the determination unit additionally determines the firing position based on the detected pressure wave. an impact sensor unit for detecting an impact of the projectile in the target object; an acoustic sensor unit for detecting a muzzle blast when the projectile is fired; and a determination unit for determining the firing position on the basis of the detected muzzle blast and the detected impact, wherein the impact sensor unit comprises a structure-borne sound detector for detecting the impact of the projectile, a sensitivity of the impact sensor unit is configured to detect the impact of the projectile fired from a weapon having a caliber equal to or greater than 5 mm, the projectile having a kinetic energy of 50 joules or more, the acoustic sensor unit additionally detects a pressure wave of the projectile when the projectile passes the impact sensor unit, and the determination unit additionally determines the firing position based on the detected pressure wave.
