BEAM-RIDER GUIDANCE DEVICE OF CONTROLLED PLANT Russian patent published in 2006 - IPC F41G7/26 

FIELD: projectile guidance systems, in particular, by laser beam.

SUBSTANCE: the transmitting channel of the guidance device is made in the form of a double-mode pulsed-periodic laser. The laser operates in the mode of free oscillation for beam guidance and in the monopulse mode for laser target indication and range finding. A polarized box is introduced between the optical system with a variable focus distance and the excess mechanism.

EFFECT: enhanced noise immunity of the projectile due to an independent use of the channels of beam guidance and laser target indication.
