METHOD FOR GUIDANCE OF GUIDED MISSILE AND GUIDANCE SYSTEM FOR ITS REALIZATION Russian patent published in 2006 - IPC F41G7/00 

FIELD: development of missile control systems, applicable in antitank missile systems.

SUBSTANCE: the method of guidance of guided missile consists in take-off of guided missile with an on-board radiation source, reception and focusing on a photodetector of radiation of the background-target situation with the legitimate signal source, discrimination of the co-ordinates of the legitimate signal source, discrimination of the co-ordinates of the guided missile and formation of the control commands for transmission to the missile. Prior to the take-off of the guided missile, the variation of the parameters characterizing characteristic property of motion of the on-board radiation source is memorized as a program value, the maximum and minimum values of the parameters characterizing the characteristic property of motion of the on-board radiation source are determined. In the process of discrimination of the co-ordinates of the on-board radiation source the parameters of motion of all the radiation sources are determined and memorized, the current parameters of motion of each radiation source are compared with the program values, and the control commands are formed in compliance with the co-ordinates of the image of the radiation source, whose motion parameters correspond to the program ones and are between the maximum and minimum values. The guidance system of the guided missile having an objective lens, radiation photodetector and series-connected co-ordinate discrimination unit and control command formation unit additionally uses a motion parameters assignment unit, series-connected memory unit, motion parameters determination unit and a comparison unit. The objective input is connected to the input of the photodetector, whose first output is connected to the co-ordinate discrimination unit, and the second output is connected to the memory unit, the output of the comparison unit is connected to the second input of the co-ordinate discrimination unit, and the motion parameters assignment unit is connected to the second input of the comparison unit.

EFFECT: enhanced quality and reliability of the process of guidance of the guided missile without any change of the construction of the missile proper, accomplished selection of the legitimate signal source among the probable optical noise, simplified construction of the control equipment, enhanced signal-noise ratio and; as a result, enhanced noise immunity of the whole control system.
