METHOD OF SOFTWARE ADJUSTABLE TARGET SUPPORT Russian patent published in 2023 - IPC G01S17/06 G02B27/00 

FIELD: tracking systems.

SUBSTANCE: invention is related in particular to methods of software-corrected target tracking and can be used on moving objects during surveillance, reconnaissance, aiming, and the use of aircraft weapons against enemy objects. The method of software-corrected target tracking is characterized by the fact that, at the first stage measurement information is registered from the on-board system of long-range and short-range navigation, the optoelectronic system, the control element of the optical system installed on the aircraft, while recording the current navigation parameters of the aircraft, orientation angles optical-electronic system, including the slant distance to the object using a laser rangefinder. At the second stage, processing of the recorded information is carried out, recalculating the values of the elevation angle, the azimuth angle of the optoelectronic system, the roll angle, and the pitch angle of the aircraft from radians to degrees and calculating the slant distance to the object without a laser rangefinder, then the linear vectors of aircraft speeds are calculated in three planes projected onto the underlying earth's surface. At the third stage, three obtained aircraft speed vectors are projected into the reference frame of the optoelectronic system with transformation of the velocity vectors along two planes. At the fourth stage, the current position of the control element of the optical system is registered. At the fifth stage, angular velocities of the elevation angle and azimuth of the optoelectronic system are calculated. At the sixth stage, mutual compensation of the calculated values of the angular velocities of the optical-electronic system, taking into account the previously recorded signals of the optical system control, is carried out; at the same time, the resulting orientation angles are transmitted to the optoelectronic system, and it is turned, which compensates for the movement of the aircraft.

EFFECT: ensuring automation of control of optoelectronic system and minimization of control errors.
