OPTICAL SIGHT OF GUIDED PROJECTILE GUIDANCE SYSTEM Russian patent published in 2004 - IPC

FIELD: optical guidance systems of guided projectiles; guided weapons with teleorientation in laser beam.

SUBSTANCE: proposed sight includes sight proper and searchlight consisting of two lasers, system for setting lasers at single optical axis, optical scanner made in form of revolving prism and zoom lens; axis of rotation of prism is matched with optical axis of lens; sight includes also non-transparent shutter fitted on mandrel of revolving prism, two optron sensors fixed in parallel relative to one of coordinates being measured in plane perpendicular to optical axis of searchlight; angle between lines connecting each sensor with axis of rotation of prism is equal to 90 deg.; outputs of first and second optron sensors are connected respectively to inputs of first and second delay circuits whose outputs are connected respectively to first and second inputs of EXCLUSIVE OR circuit and to first and second inputs of first permanent storage; output of EXCLUSIVE OR circuit is connected to first inputs of time counter and channel switch; output of time counter is connected to third input of first permanent storage whose output is connected to first input of code-time converter whose second input is connected with output of reference generator and second input of time counter and output of code-time converter is connected to second input of channel switch whose outputs are connected respectively to inputs of first and second lasers; provision is made for second permanent storage, first and second registers. Analog-to-digital converter and temperature sensor. Output of temperature sensor is connected with input of analog-to-digital converter whose output is connected with fifth input of second permanent storage; outputs of first and second registers are connected respectively with third and fourth inputs of second permanent storage whose first and second inputs are connected with outputs of first and second optron sensors, respectively. Output of second permanent storage is connected with information inputs of time counter.

EFFECT: enhanced accuracy of guidance in wide range of surrounding temperatures.
