FIELD: guided missile optical guidance systems, applicable in guided weapon systems with teleorientation in a laser beam. ^ SUBSTANCE: the optical sight of the guided missile guidance system has a coaxially installed sight and a projector including two injection lasers, whose emitting areas are positioned perpendicularly to the axes of the measured co-ordinates, system of laser emission ejection to a single optical axis, an optical scanner in the form of a rotating prism and a zoom lens installed in succession in this axis. The axis of prism rotation is matched with the lens optical axis. The sight has also a nontransparent shutter installed on the cell of the rotating prism, two optronic sensors fixed in parallel with one of the measured co-ordinates in the plane perpendicular to the projector optical axis, the angle between the lines connecting each sensor to the axis of rotation of the prism makes up 90 deg. The outputs of the first and second optronic sensors are connected respectively to the inputs of the first and second delay circuits, whose outputs are connected respectively to the first and second inputs of the exclusive OR circuit, as well as to the first and second inputs of the permanent storage, the output of the exclusive OR circuit is connected to the first inputs of the time counter of the channel switch. The output of the time counter is connected to the third input of the permanent storage, whose output is connected to the first input of the code-to-time converter, whose second input is connected to the output of the frequency standard and the second input of the time counter. The output of the code-to-time converter is connected to the second input of the channels switch, whose outputs are connected respectively to the inputs of the first and second lasers, use is made of the first and second pulse counters, whose first clock inputs are connected to the output of the frequency standard, the carry output of the first pulse counter is connected to the clearance input of the second pulse counter, whose information outputs are connected to the fourth input of the permanent storage. ^ EFFECT: enhanced range of guidance of the guided missile. ^ 3 dwg |
