ABSTRACT:
A system for the reception of guidance orders for a guided missile in optoelectronic mode includes an optoelectronic sensor receiving a guidance signal, transmitted by an optical beam, from a firing control station. There is provided an unpropelled aerodynamic carrier (1) connected to the body of the missile by a flexible link (7), enabling it to be pulled by the missile during the propulsion phase of this missile. The assembly is configured so that, under the effect of this traction, the aerodynamic carrier takes an angle of attack (.alpha.) enabling it, in a transversal direction, to move away from the body of the missile by a distance (x) greater than the extent of a zone (4) in which the transmission of the beam is disturbed by the hot gas jets from the propellant of the missile. The aerodynamic carrier is provided, at its rear end, pointed in the direction of attack of the optical beam, with an optical transducer capable of picking up the optical guidance signal transmitted by this beam (3). The flexible link (7) preferably includes an optical fiber, optically coupled at one of its ends to the transducer positioned on the aerodynamic carrier, so as to inject the optical signal received by this transducer into the fiber. At its opposite end, this optical fiber is optically coupled to the optoelectronic sensor (2) positioned in the body of the missile, so that this sensor receives, from the fiber, the received optical signal injected into said fiber at its other end, and converts this received optical signal into an electrical guidance signal.
