METHOD FOR GUIDING SELF-GUIDED AMMUNITION UNDER LASER INFLUENCE Russian patent published in 2023 - IPC F42B15/01 F41G9/00 

FIELD: guided munitions.

SUBSTANCE: invention relates to systems of fire destruction of objects by guided munitions. The method for targeting a self-guided munition (TSGM) under conditions of laser exposure, in addition to the known method, includes the use of two matrix photodetectors (MPD) of damaging laser radiation (DLR), including one line of coordinate-referenced photosensitive elements (CPPE) placed perpendicular to each other in the plane perpendicular to the optical axis of the optical-electronic coordinator (OEC), at the maximum distance from the optical axis of the OEC and at the minimum distance from the focal plane of the OEC, the fields of view are oriented to the optical axis of the OEC. The MPD of the DLR source radiation scattered sideways by the OEC gas medium is received and the coordinates of the CPPE of the DLR are determined, the output signal of which exceeded the threshold value and the parameters of the angular mismatch of the flight direction of the TSGM and the direction to the DLR source. In case of inoperability of the photodetector, the TSGM flight trajectory to the DLR source is corrected according to the values of the angular mismatch parameters of the TSGM flight direction and the direction to the DLR source, obtained using additional MPDs.

EFFECT: increasing the effectiveness of the use of TSGM.
