GUIDED MISSILE CONTROL METHOD Russian patent published in 2011 - IPC F41G3/22 F41G5/14 

FIELD: weapons and ammunition.

SUBSTANCE: method involves alignment of two sighting lines with target at sharp angle between them, capture of controlled missile, measurement of deviations of controlled missile from both sighting lines, transmission of control commands to missile, which correspond to those deviations, supply to missile control members of the signal corresponding to sum of both control commands, and periodic change of brightness of laying marks of sighting lines. Stability margins of each guidance system and the smallest one of them are pre-determined as to phase, and missile control information areas are formed and aligned with each sighting line. Roll angles of each of them and relative roll angle between them is measured relative to the shooting plane, values of smaller stability margin as to phase and relative roll angle are compared between missile control information areas, colour of laying marks is changed if value of relative roll angle between missile control information areas exceeds the smallest value of stability margin of one guidance systems. Periodic variation of brightness of laying mark of each sighting line is performed at available capture of missile with the appropriate guidance system, availability and duration of conjoint capture of missile is determined simultaneously in both guidance systems and frequency of variation of brightness of both laying marks is doubled by this time.

EFFECT: increasing guidance efficiency of controlled missiles, protection of guidance systems and shooting objects.
