FIELD: radiolocation and communications, namely, systems for transmitting radiolocation information to remote indicators, possible use in radiolocation complexes for transmitting and displaying air situation on remote indicators. ^ SUBSTANCE: in accordance to the invention, fiber-optic system for transmitting information in radiolocation station with remote indicators additionally includes, on radiolocation station side, between impulse generator and impulse stack generator, a divider by two, and between universal register with N bits and fiber-optic communication line, a modulus adder and a D-trigger, while first input of modulus two adder is connected to output of shift register, and second one - to output of modulus two adder, output of modulus two adder is connected to first input of D-trigger, and output of impulse generator is connected to second one, on the side of remote indicators fiber-optic communication line output is connected simultaneously to inputs of delay element, AND circuit, OR-NOT circuit, output of delay element is connected to second inputs of AND circuit and OR-NOT circuit, output of AND circuit is connected to R-input of the trigger, and output of OR-NOT circuit is connected to input of the same trigger, output of which is connected to the input of modulus two adder and to inputs of circuit for selecting start signal and of shift register simultaneously, second input of adder is connected to middle point of delay element, output of modulus two adder is connected to clock impulse input of impulse stack generator. ^ EFFECT: increased interference resistance of transmission due to generation of group signal with constant average power and due to removal of high stability quartz generator at receiving side, possible selection of synchronization impulses directly from the message being transmitted. ^ 5 dwg |
