RADIO DISTANCE METER Russian patent published in 2000 - IPC

FIELD: radio engineering, in particular, high-precision measurement of distance between arbitrary mobile objects in arbitrary moment. SUBSTANCE: device has autonomous active unit, which is designed as secondary station, which has serial circuit of second antenna, second isolation unit, second receiver, second synchronization unit, which generates time substitution, second generator of linear modulation pulses, second generator of sounding and heterodyne signals, which second input is connected to second output of second synchronization unit, and second amplifier, which output is connected to first input of second isolation unit. Device implements partial measuring distance method using multiple-scale measuring system and special active re-reflection. EFFECT: extended region of unambiguous solutions, without precision losses in real time, increased stability to noise. 1 dwg
