Abstract

In this system the fire-control station) 1 comprises : - means (40 to 45 Fig 4) for tracking a target and defining a line of sight LV ; - means (33 to 39 Fig 4) for scanning with a laser beam (3) a guidance cone 5 whose axis of symmetry AS is locked to said line of sight LV , said cone 5, being made up of elemental cells (e.g. 9, 9' Fig 2) successively illuminated by said beam 3, the beam being deflected by two acousto-optic deflectors (37, 37' Fig 4) in two orthogonal planes; - means for modulating said beam 3 according to a binary sequence (Fig 3) representing said Cartesian coordinates of the cell which is illuminated; and the projectile includes : - means for receiving said laser beam 3 , for demodulating it and for decoding the coordinates; - means for determining a trajectory correction such that said projectile comes closer to the axis of symmetry AS of said guidance cone 5. The beam may carry a message. The effective beam size is controllable in dependence upon range (Fig 5).
