Abstract

Lenses of sighting device that provide aiming at fast moving targets without telemetering distance of target and without estimation of flight elements thereof, fig. 5, solve the problem of determination of radius r of outrunning, i.e. angle of outrunning thereof, by using the angle speed W of the, point of outrunning in a roof plane. Herewith, from the procedure of determining elements of shooting eliminated is telemetering of distance up to the target and is eliminated even the estimation of elements on characteristics of flight of the target along its path. Consequently, on the lens (7) materialized are spirals (4), (5) and (6) of outrunning, defined in the function of angled speeds WWp, of the point of outrunning, and on the lens (8), circle (10), in its center, and perpendicularly to it, a half-line (9). When sighting and aiming it is needed that the picture (12) of the target is brought into cross-section of the half-line 9) and that spiral of outrunning where half-line (9) is concordant to longitudinal axis of the picture of the target in the visible sight of the sighting instrument so as to direct the pipes of the system for sighting in the target of overrun. Thereby, lens (8) in the visual sight of sighting instrument is rotated in the function of simulated angle FP, and the lens (7) in comparison to lenses (8) in function of alteration of the angle of speed Wp. Applied method enables projection of discreet artillery air defense systems having highly efficient aiming features.
