METHOD FOR SELECTION OF SEA TARGET USING AIRCRAFT OPTOELECTRONIC SYSTEM Russian patent published in 2020 - IPC G01S3/06 

FIELD: guidance systems.

SUBSTANCE: invention relates to autonomous final guidance systems of aircrafts (AC). Said result is achieved by the fact that the optoelectronic system (OES) of AC includes a passive thermal imaging channel (TIC) with a matrix photodetector (PD) and an active pulsed laser channel (LC) with co-directional viewing axes, spectral range of LC operation is located inside spectral range of TIC operation, LC operation is started after determination of bearing on sea target (ST) by means of TIC or other (all-weather) onboard selection channel, device for outputting and receiving laser radiation LC is stabilized by course and pitch angles relative to inertial coordinate system AC, laser radiation divergence is in range of 0.1 to 8.0 mrad, laser pulse repetition frequency is set at the level of not less than 10 Hz, and the received TIC PD image is synchronized with LC radiation to provide operation on a time line related to the range to ST obtained by the receiving LC device, wherein the presence of ST is determined by its simultaneous fixation along bearing with the receiving devices TIC and LC.

EFFECT: selection of ST of OES of final guidance of AC, including under conditions of natural and intentional interference, by means of integration of passive thermal imaging and active laser channels.
