FIELD: armament and military equipment, in particular, protection of fighting vehicle against aerial attack aids, as well as firing, for example, in mountain conditions at elevations (depressions) of the target location with respect to the launcher. ^ SUBSTANCE: the accuracy and respectively the effect of fire of the fighting vehicle is enhanced firstly at firing of a small-caliber gun armament at aerial targets, especially in the near zone, as well as at a flight of the target at high altitudes; secondly, at firing of a gun of moderate (and low) ballistics in mountain conditions at elevations (depressions) of the target with respect to the gun (launcher) location. The known method for firing of a fighting vehicle at target includes the detection and identification of the target, tracking with determination of the target coordinats and parameters, determination of angular corrections: kinematic corrections for target and carrier motion, ballistic corrections (aiming angle alpha0 and derivation angle beta0), cross wind Wz and longitudinal Wx ballistic wind speed corrections, sight and fighting machine parallax corrections from mathematical expressions, summation of them respectively in the horizontal and vertical channels with due account made for the bank angle and permanent deviation during firing with due account made for the computer angular corrections of the launcher barrels relative to the sight line. According to the invention, preliminarily before the firings, proceeding from the firing table, the dependence of the generalized parameter of the function of resistance on the range of fire A(D) for the projectile of each type is determined for the whole probable range of target elevation epsilon. After determination of the ballistic corrections, up to their summation, fighting vehicle trim theta is additionally determined, the summary target elevation with due account for fighting vehicle trim theta is determined, and sight angle alphaepsilon is determined, with due account for target elevation epsilon, from the first mathematical expression. The total angular correction in the vertical channel is determined with due account made for obtained angle alphaepsilon by way of its algebraic summation with the rest corrections. ^ EFFECT: enhanced accuracy and efficiency of fire of the fighting vehicle. ^ 4 cl, 16 dwg |
