FIELD: weapons and ammunition.SUBSTANCE: device for blasting ammunition at the specified distance from target includes two and more receiving-emitting channels, each of which includes an electronic unit, an optic emission pulse source and a photoreceiver, which are connected to the electronic unit. Optic axes of the optic emission pulse source and the photoreceiver, which form a receiving-emitting channel, are directed at an angle to ammunition axis in the movement direction and located with an offset relative to each other, mainly parallel or almost parallel. Receiving-emitting channels are arranged about ammunition longitudinal axis. An angle between emitters of adjacent receiving-emitting channels in radial direction is chosen so that light beams of emitters do not intersect between each other. Distance between beams of neighbouring emitting channels at the required distance of the target detection is equal to/approximately equal to minimum size of the target.EFFECT: improving probability of detection of small-size targets; providing high accuracy of determination of the moment when ammunition reaches the specified actuation distance; enhancing protection against optic and small-size interference, and reducing weight-and-dimensional characteristics.2 cl, 1 dwg |
