OPTICAL RADAR Russian patent published in 1997 - IPC

FIELD: radar engineering. SUBSTANCE: optical radar provides for reduction of awkwardness without reducing the scanning rate due to introduction of a reverse rotation drive as the second drive, second azimuth marker transmitter, growing sawtooth voltage generator, dropping sawtooth voltage generator, electro-optical deflector, reflecting mirror, double-beam indicator with a linear sweep, control pulse processing and generating unit consisting of two coincidence gates, two symmetrical flip-flops and an amplifier; the reverse rotation drive is directly coupled to the second prism and second azimuth marker transmitter, having an output connected via the first input of the control pulse generating unit to the first input of the first coincidence gate, having a second input and output connected respectively to the output of the second symmetrical flip-flop and to the output of the first symmetrical flip-flop, as well as via the first output of the control pulse generating unit, dropping sawtooth voltage generator to the first input of the double-beam indicator with a linear sweep, having an optical communication with the processing unit, and the second, third and fourth inputs connected respectively to the output of the first laser receiver, output of the second laser receiver and via the growing sawtooth voltage generator, second output of the control pulse generating unit to the output of the second coincidence gate also connected to the input of the second symmetrical flip-flop, and having the first and second inputs connected respectively via the second input of the control pulse generating unit to the output of the first azimuth marker transmitter and to the first output of the first symmetrical flip-flop, having a second output connected via an amplifier, third output of the control pulse generating unit to the input of the electro-optical deflector connected via the optical input to the optical output of the laser transmitter, and via the first and second optical inputs respectively to the first optical input of the first vibrating mirror and to the optical input of the reflecting mirror, whose optical output is coupled with the optical input of the radiation source. EFFECT: reduced awkwardness and enhanced quality. 4 dwg
