OPTICAL DIRECTION FINDING SYSTEM OF ALL-ROUND VIEW Russian patent published in 2021 - IPC G01S5/16 

FIELD: weaponry.

SUBSTANCE: invention relates to optical direction finding systems of sector and circular view, providing detection, tracking, processing of coordinates of various ground, water and air objects. The result is achieved due to the fact that the multichannel optoelectronic system for review and tracking includes N mechanically connected review and auto-tracking modules with overlapping of the scanned space in the azimuthal plane, the review module is made in the form of a gyro-stabilized multispectral optoelectronic unit, including a television channel of the visible range, a television channel near infrared range (0.9 - 1.7 mcm) and a thermal imaging channel in the middle infrared range (3 - 5 mcm) or far infrared range (8 - 12 mcm) with the same angles of the fields of view; the auto-tracking module is made in the form of two independent gyro-stabilized optoelectronic units with installed thermal imaging and rangefinder channels with the ability to simultaneously track at least 2 objects in three coordinates (in elevation, azimuth and range) in a sector view and less than 2N objects in a circular view of space.

EFFECT: increased range, increased accuracy of determining the coordinates of objects in conditions of shaking and rolling, providing a continuous view of space and simultaneous tracking of at least 2 objects in 3 coordinates (azimuth, elevation and range) within a certain sector or at least 2N objects at circular view, reducing the time of space survey, ability to highlight objects against the background of interference.
