CONTROL SIGNAL SHAPER FOR FINAL CONTROL ELEMENT OF OPTOELECTRONIC TRACKING SYSTEMS Russian patent published in 1997 - IPC

FIELD: optoelectronic, including infra-red, tracking systems with gyro stabilized field of vision. SUBSTANCE: shaper having pulse amplifier incorporating automatic gain control (AGG), amplitude detector, and selective amplifier is provided, in addition, with double-ended limiter, first and second switching members, band filter, low-frequency filter, nonlinear element, phase shifter, automatic noise control, and adder. Main of pulse amplifier is connected to output of photodetector series-connected to double-ended limiter, first switching member, band filter, amplitude detector, nonlinear element, phase shifted, and selective amplifier whose output is connected to input of final control element. Pulse amplifier output is connected via second switching member and AGG to first input of adder whose output is connected to parametric input of pulse amplifier. Band filter output is connected through automatic noise control to adder second input. Control inputs of first and second switching members are connected to outputs of control device. Newly introduced units provide for desired tracking accuracy throughout entire speed variation range of sighting line dew to shaping control signal of desired waveform with respect to dead and linearity zones as well as for adapting optoelectronic tracking. System to optical resolution of radiation sources within system field of vision due to ensuring self-excited oscillations in tracking circuit. EFFECT: improved tracking accuracy and noise immunity of optoelectronics tracking system. 1 dwg
