Abstract
System for guiding a missile in a direction of sight, comprising, at emission, a source of emission producing a light beam of which the axis defines the direction of sight and a device for modulating the beam emitted, and, on the missile, at least one photodetector and a processing circuit for determining, from the output signal from the detector, at least one coordinate of the missile with respect to the direction of sight, said coordinate being applied to the control surfaces of the missile in order to control the path of the missile on the direction of sight. The modulation device comprises a sight in the form of a band comprising repetitive motifs, a movement of translation at constant speed being created between the beam and the sight, in a direction perpendicular to the axis of the beam, each motif comprising opaque and transparent parts, the opaque and/or transparent parts having a length (measured in the direction of displacement) which varies according to the height in question. A time base is provided for determining the two coordinates of the missile.
