What is a Ground Penetrating Radar (GPR) ?
GPR is based on “stacking” a series of ultra-wide band electromagnetic pulse emissions that are sent directly into the subsurface. The Radar captures information about the different conductive properties of the lithology directly under the device.
The radar records the conductive differences, and shows - in section view - a geophysical based interpretation of different lithological interfaces, layers or objects.
Old GPR technology uses a transmitter with a power transistor voltage of about 50v. Old GPRs were limited to only being effective in light soils with low signal attenuation (for example dry sand or frozen soils). The depth of effective scanning for old GPR technology is limited to only a few meters depth, and scanning was not possible at all if the geological section had wet clays or loam.
Why Loza Radar represents a big improvement
Depending on the parameters of the subsurface, Loza Radar can be configured to survey the subsurface lithologies and structure to a depth of a few meters to hundreds of meters.
The increase in depth penetration by Loza is achieved through significantly enhanced energy potential. Loza is effective in environments with high conductivity, (including clay, areas of high salt content) and even through water.
Loza Radar has:
✓ Increasing the penetration depth is made possible by reducing the frequency of the signal.
✓ The transmitter power has been increased by a factor of over 100,000 times;
✓ The transmitter uses a pulse via a high-pressure hydrogen discharge, and operates in stand-alone mode without synchronization, thus avoiding the requirement for connecting lines;
✓ Stroboscopic transformation is replaced to direct detection of signal;
✓ Loza Radar uses RC-loaded dipoles to ensure the exclusion of interference in the received signal that suppresses weak signals, whilst also permitting the reception of strong signals;
