FIELD: armament and military equipment, in particular, protection of fighting vehicle against air attack aids, for example, with the aid of machine-gun (gun) mountings.
SUBSTANCE: according to the first modification, detection and identification of the target, accompanying with determination of the target co-ordinates and parameters, determination of angular corrections their summation respectively in the training and elevation channels with due account made for the crosslevel angle are accomplished. Prior to determination of the angular corrections, the angular velocity of the sight line is found by differentiation of the angles of inclination of the sight line respectively in the training and elevation channels. According to the second modification, detection and identification of the target, accompanying with determination of the target co-ordinates and parameters, determination of angular corrections, their summation respectively in the training and elevation channels with due account for the crosslevel angle are accomplished. Prior to determination of the angular corrections, information on the angle of inclination of the sight line is accumulated in the form of a great number of points for each channel. Then, the function characterizing the sight line by polynomial is approximated. Systematic and random errors of the reproduced derivative of the angle of inclination of the sight line are determined, the order of its approximation for the next interval of prediction of the angular velocities is selected proceeding from the rational relation of the systematic and random errors, and the angular velocity of the sight line in the training and elevation channels respectively.
EFFECT: enhanced accuracy and efficiency of fire of the fighting vehicle, especially at high-speed (air) targets due to enhanced accuracy of determination of the angular velocity of the sight line.
