METHOD FOR GUIDANCE OF GUIDED MISSILE AND GUIDANCE SYSTEM FOR REALIZATION Russian patent published in 2005 - IPC

FIELD: development of missile control systems, applicable in anti-tank missile complexes.

SUBSTANCE: the method for guidance of guided missile includes launching of the guided missile with an on-board radiation source, reception of the luminous flux from the on-board radiation source of the guided missile by an aerial camera separation of the co-ordinates of the on-board radiation source of the guided missile, determination of the co-ordinates of the guided missile and formation of the control commands, focusing of the luminous flux from the on-board radiation source of the guided missile is accomplished on a matrix photodetector. In the process of separation of the coordinates of the on-board radiation source of the guided missile the video frames of the background situation together with the on-board radiation source are formed. The space exposed to the on-board source of radiation is determined, the center of the space exposed to the on-board radiation source, the center of the space exposed to light by the on-board radiation source, the cell of the matrix-type photodetector is determined, which is the center of the space exposed to the on-board radiation source, and the position of the cell of the matrix-type photodetector is determined, which is the center of the space exposed by the on-load radiation source. The task is also solved by the fact that the guidance system of the guided missile having an objective lens, photodetector, series-connected co-ordinate separation unit and a command formation unit additionally uses series-connected unit of separation of illuminated space and on unit of computation of the center of illuminated space. The photodetector is made in the form of a matrix-type photodetector, installed in the focal plane of the objective lens, the output of the matrix-type photodetector is connected to the unit of separation of the illuminated space, and the output of the unit of computation of the center of the illuminated space is connected to the unit of co-ordinate separation. In the offered method of guidance of guided missile the center of the illuminated space by the radiation source may be calculated as a power center.

EFFECT: enhanced quality and reliability of the process of guidance of the guided missile without any change of the structure of the missile proper, selected source of the useful signal in intensity of radiation, enhanced antifamming of the entire control system.
