TELEVISION CAMERA CONTROL SYSTEM Russian patent published in 2003 - IPC

FIELD: controlling angular position of television cameras and acoustic means on mobile objects such as submarines and flying vehicles. SUBSTANCE: newly introduced in control system to generate high-quality control signal for TV camera during its tracking a target are tracking-and-storage element whose first input is connected to output of first multiplying unit and output, to second input of first adder; series-connected second relay element; and second multiplying unit whose second input is connected to output of division unit and output, to input of first arctangent function generator; nonlinear element whose input is connected to input of second relay element and to output of adder and output, to second input of division unit; and also switch whose first and second inputs are connected to position setting element output and to second adder output, respectively, and third input, to output of mode-of-operation switch and to second input of tracking-and-storage element and output, to first input of error meter. EFFECT: enhanced precision of camera tracking the target detected with underwater apparatus moving above this target. 2 dwg
