OPTICAL SIGHT OF MISSILE GUIDANCE SYSTEM Russian patent published in 2002 - IPC

FIELD: optical guidance systems of self-propelled projectiles, applicable in guided weapon systems with tele-orientation in a laser beam. SUBSTANCE: the guidance system optical sight has sighting, range-finding channels and a missile guidance channel consisting of optically matched radiation source, modulator, plane-parallel plate provided with a traversing mechanism consisting of a motor with a reduction gear and an initial position sensor with a motor control circuit, and an optical system with a variable focal length, besides, the sight uses also a missile-type selection device, programmer, non-linear rotation transmission mechanism mechanically linked with the motor reduction gear and the plane-parallel plate, provided with a return device coupled to the programmer and motor control circuit. The output bus-bar of the missile-type selection device is coupled to the programmer inputs, whose other inputs and outputs are connected to the control bus-bar of the missile guidance system, one more input of the programmer is connected to the initial position sensor, and one more input-to the output bus-bar of the range-finding channel, whose input is connected to the control bus-bar of the missile guidance system. EFFECT: enhanced noise immunity of the guidance system. 4 cl, 4 dwg
