Zusammenfassung: | An apparatus for detecting a projectile, and for determining the position at which the projectile impinges on a target comprises a framework covered with sheets of material capable of being penetrated by a projectile to form an anechoic chamber, and transducers (56, 58, 60) located within the chamber on an arc of a circle to detect pressure or shock waves within the chamber generated by the projectile, and means (76) to measure the time differences between the instants of reception of the pressure or shock waves by the transducers, and means (80) for calculating the position of the projectile. |
