OPTICAL RADAR Russian patent published in 1997 - IPC

FIELD: measurement technology. SUBSTANCE: first and second truncated diaphragms are installed between turned focusing objective and first photoreceiver and focusing objective and second photoreceiver, respectively. Use is also made of range finding unit consisting of two computers, scale-of-two circuit, two constants input panel, and multiplier. In this case, first computer output is connected to first input of second computer through range finding unit. Second input of second computer is connected to first output of two constants input panel, and its output is connected to first input of third computer via scale-of-two circuit. Third computer has second input connected to first output of the above-indicated two constants input panel and output connected to first input of multiplier second input of which is connected to second output of two constants input panel, and output is connected to indicator input through output of range finding unit. EFFECT: higher accuracy of determination. 2 dwg
