FIELD: geophysics. SUBSTANCE: geophysical radar is related to equipment for geophysical prospecting with use of high-frequency electromagnetic waves and can be used in search for mineral resources, for engineering service lines and other latent inhomogeneities in examined layer of ground surface. Geophysical radar includes control and processing unit, interface, transmitter, transmitting antenna, first mixer of stroboscopic converter, first gate former, receiving antenna, receiver, second gate former, second mixer of stroboscopic converter, first delay line, flip-flop, key, sound indicator, liquid-crystal indicator, second delay line, subtractor, integrator, divider, reference voltage former and comparator. EFFECT: enhanced reliability of detection and identification of objects under surface at various depth of bedding thanks to exclusion of variations of electromagnetic field. 1 dwg |
