SUBSURFACE RADAR Russian patent published in 2000 - IPC

FIELD: subsurface radiolocation, in particular, means for determining the location and shape of discontinuities and inclusions in condensed media. SUBSTANCE: the device has a retunable radio-frequency generator, radio-frequency signal receiver, receiving and transmitting antennas, the receiving and transmitting antennas are provided with an input system of coordinates of the examined surface, the transmitting and receiving antennas are combined in a common horn of round section, which accommodates a transmitting and two receiving electrodes. The transmitting electrode is located in the horn radius, one receiving electrode is located perpendicular to the transmitting one, and the other receiving electrode-opposite the transmitting one. Frequency returning of the radio-frequency generator is accomplished within the range up to 24 per cent. The horn antenna is provided with a coordinate input system. EFFECT: enhanced resolving power. 3 dwg
