device for identification at the point of impact of a projectile

摘要

A multifunctional measuring and search system monitors the intrusion of objects, in particular fishing vessels (20), into a safety zone (18), and additionally monitors the impact of projectiles within an impact zone (16) by means of a radar device (26) which is put into a splash spotting mode at triggering of a shot so that the location of the column of water and spray may be detected. By means of memorizing a recovery or salvage cadastre, i.e. the topography and nature of the ocean floor, and taking into consideration the variable water level it is possible to compute and to display the location of impact and the penetration depth of said projectiles on the ocean floor when taking into account the impact angle resulting from the projectile ballistics and the velocity of said projectiles.
