METHOD FOR HOMING OF CONTROLLED MISSILE Russian patent published in 2010 - IPC F41G7/20 

FIELD: weapons and ammunition.

SUBSTANCE: according to invention, two lines of aiming are matched with the target with a sharp angle between them. Deviations of controlled missile from both aiming lines are measured by homing systems in process of its flight. Control commands that correspond to these deviations are automatically generated and sent to missile. Signal that corresponds to sum of both control commands is automatically generated and sent to control elements of missile, and luminance of aiming line marks is periodically changed. At the same time periodical change of aiming mark luminance in each aiming line is done when controlled missile is captured by according aiming system. Availability and duration of joint capture of controlled missile are detected in both systems of aiming, and frequency of both aiming marks luminance variation is doubled by this time.

EFFECT: improved efficiency of aiming.
