Abstract (en)
The object of the invention is to provide a cheap and compact shooting target system which is able to automatically retrieve information relating to the point of impact of a projectile in a target. The object is achieved by a shooting target system comprising: - a target (11; 21; 31) composed by a material in which shock waves arise and propagate when hit by a projectile; - a first shock sensor (10a; 20a; 30a) arranged to detect said shock waves; - at least a second shock sensor (10b-c; 20b-f; 30b-d) arranged at a distance from said first shock sensor, and - calculation means (12; 22; 32) for determining at least a first time-delay between the detections of the shock wave by the first and the at least second sensor, and for calculating information relating to the point of impact of the projectile in the target based on said at least first time-delay.
