Forces of pulses are connected to the output of a generator of personnel pulses.

FIG. 1 is a block diagram of the device 20; in fig. 2 - pulse diagrams from various circuit elements.

A device for automatic tracking of an object is connected to a television sensor 1 connected to a generator-25 of 2 frame pulses and a generator of 3 horizontal pulses, a delay element 4, the first element 5, the second element 6, a third element 7, the fourth element 8, the fifth element And 9, the first driver 10 control pulses, the second driver

11 control pulses, the first pulse counter 12, the second pulse counter 13, and the actuator 14. In FIG. 2 also denotes: 15 - ^L '^> signal from the output of the television sensor, 16 - signal of the output of the delay element, 17,18,19,20 - formation processes, 21 - signal at the output of the element And, 22 - from the output of the television 40 sensor, 23 - from the output of the delay element, 24 - the pulses from the output of the driver of the control pulses, 25 control pulse, 26 - at the output of the element I.

The And delay element divides the interval between the pulses generated by the generator of 3 horizontal pulses, and five zones. The pulses corresponding to the 1st, 3rd and 5th zones are fed to the 5θ inputs of the three elements And 5.6.7, the other inputs of these elements are fed from the television sensor 1, which is a pulse corresponding to the regulating parameter or interference so that the impulse corresponding to the regulating parameter is present at the initial moment in the third zone.

The pulses from the extreme zones of the 1st and 5th zones are equal in duration between the end 60 of the 1st zone and the beginning of the impulse of the adjustable parameter, and the height equal to the duration between the end of the impulse of the controlled parameter and the beginning of the first zone. Each impulse is about ~ 65

Forming shapers of 10 or 11 control pulses are compared in duration with control mppuls that are in the intervals between the end of the first zone and the beginning of the pulse, the controlled parameter, and between the end of the adjustable parameter and the beginning of the 3rd zone. Since the polarity of the control pulses is reversed by the polarity of the pulses between the respective edges of the adjustable parameter and the corresponding edges of the zones, when the adjustable parameter in the middle zone approaches any extreme zone. .to a sufficiently close value, at the output of the corresponding shaper 10 or 11 control pulses, a pulse of the same polarity as the control pulse is obtained. This impulse, having passed the corresponding element AND 8 or 9,. 12 or 13 pulses are fed to the counter, which, having calculated some of them, issues a command to the actuator to change the position of the adjustable parameter.

At the end of the television line, a reset pulse is sent to the control pulse formers from the 3 row pulse generator, and at the end of the frame, a reset pulse is sent from the 2 frame pulse generator to the pulse counters 12 and 13, which return them to their original position.

The use of the proposed device improves the noise immunity and accuracy of object tracking.
