Georadar GROT-11.
a) - unproccessed binary frame, the arrows point to strata bounds.
b) - strata bounds are highlighted by red lines.
c) - different colors show different soils.

Example of profile for heavy soil.
Georadar GROT-10.
Range 512 ns.
Measurements are carried out in the binary mode in the arid period.

Old burial place on the cemetery.
Left - full-wave frame, right - binary frame.
The search for burials was produced according to the following criteria:
dimensions - 1x2m;
depth - 1.5-2.5m;
direction East-West.
Burial is indicated by red pointers. Excavations in the accuracy confirmed the presence of
burial at the indicated place.

Search for polyethylene pipe.
Georadar method makes it possible to find the position of the underground communications made
from the very different materials, including the polymeric. In this case there is no need for
connecting equipment to the routes of underground communications. A study is conducted from
the surface, but surface itself remains not disrupted.
Figure shows radar data, obtained during the search for polyethylene pipe (D=110mm). The
diffracted wave from the desired object is distinctly visible here. The double transit time
of radio wave is 24 nanoseconds. So it is possible to draw the conclusion that the pipe is
located on depth 1.2-1.3 m.
The work for the search was carried out during June 2002 in Tolstopal'tsevo (Moscow).

Investigation of communications on building objects.
Main peculiarities of such kinds of works are connected with a lot of air hindrances on
building objects, so shielding antenna are demanded. The picture shows radar data with
collector position marked at the depth 5.5 metres.

Investigation of mineral deposits with georadar GROT-11.
Main peculiarity is connected with big power of overlapped thickness. The pictures show maps
of top and bottom of minerals built on the base of georadar investigations.
