GEOPHYSICAL RADAR Russian patent published in 1998 - IPC

FIELD: search for mineral resources, engineering communications and hidden inhomogeneities in examined undersurface layer of the Earth surface. SUBSTANCE: geophysical radar includes special calculator 1, interface 2, transmitter 3, transmitting antenna 4, first mixer 5 of stroboscopic converter, first gate former 6, receiving antenna 7, receiver 8, second gate former 9, second mixer 10 of stroboscopic converter, delay line 11, flip-flop 12, key 13, digital-to-analog converter 14, amplifier 15, analog-to-digital converter 16, sound indicator 17 and liquid crystal indicator 18. EFFECT: increased precision and resolution by depth thanks to exclusion of reflections from surface "air-ground " and use of sequence of radio pulses with small number of periods of high-frequency vibrations in each of them. 9 dwg
