ABSTRACT:
The disclosed device can be used to determine coordinates expressing the angular deviation between the direction in which a missile is located and a line of sight in which a target is located. The device comprises means to project and shift an image on a linear senor, in such a way that the field of acquisition of the homing device has a section, by a plane perpendicular to the line of sight, that is ring-shaped having a diameter corresponding to a wide field aperture at the moment when the missile is launched, so that the missile is definitely intercepted in the field of acquisition, and then having a diameter that is variable as a function of time in such a way that the ring follows the missile as and when it approaches the line of sight through the action of a remote control system or a directive beam system. Finally, the section of the field is reduced to a simple disk, corresponding to a field having a very small angular aperture, giving a better range than standard homing devices and giving a low probability of false alarms arising out of the presence of the sun or of decoys. The device can be applied to weapons systems.
