METHOD OF GUIDED MISSILE HOMING Russian patent published in 2012 - IPC F41G3/22 F41G5/14 

FIELD: weapons and ammunition.

SUBSTANCE: method includes matching a stabilised sighting line with a target, launching a guided missile and its capture by a homing system, measurement of altitude and direction deviations of the guided missile from the sighting line by the homing system, transfer of control commands to the missile that correspond to these deviations, supply of signals corresponding to these commands to missile control facilities. The stabilised sighting line is aligned with an optical axis of a guided missile coordinator, angles of list caused by carrier's manoeuvring are measured in metering axes of the coordinator's field of view, a control command is generated along altitude as a sum of products of guided missile deviation along altitude by a cosine of a list angle and deviation of a guided missile along course by a sine of a list angle. The control command along direction is generated as difference of products of guided missile deviation along direction by a cosine of list angle and guided missile deviation along altitude by a sine of list angle. For the time of guided missile capture, brightness of a sighting mark of the stabilised sighting line is reduced down to 60% from the initial level, and components with frequency of more than 1.5 Hz are excluded from the control commands.

EFFECT: higher efficiency of homing by increasing noise immunity of a visual channel, accurate homing of a guided missile and introduction of additional information on parameters of the process of guided missile homing to a target.
