ABSTRACT:
System for guiding a missile, comprising a source emitting a light beam of which the axis defines the direction of sight, at least one modulation sight placed in the path of the beam, means for producing a relative movement of rotation between the sight and the beam, and on the missile, at least one detector and a calculating circuit for determining, from the output signal from the detector, the coordinates of the detector with respect to the direction of sight.
The control surfaces of the missile are actuated as a function of said coordinates with a view to controlling the path of the missile on the direction of sight.
The modulation sight comprises transparent and opaque, and possibly semi-transparent sectors, defined by curves symmetrical with respect to the center of the sight, at least certain of these curves having for equation f (.rho., .theta. modulo .pi.)=O, where .rho.varies monotonically as a function of .theta., and defining 2n angles at the center which are equal whatever the radius in question, so that the duration of relative illumination of the detector remains equal to 50%, whatever its positio
