"Zond-12c" georadar is a portable digital subsurface sounding radar carried by a single operator. The unit is designed for solving a broad range of geotechnical, geological, environmental, engineering and other tasks wherever nondestructive operational environmental monitoring is needed. In the sounding process, the operator is getting real-time information as a radiolocation profile (sometimes also referred to as radargram) on a display. At the same time, data are recorded on a magnetic disc for further use (processing, printout, interpretation, etc.).

Complete georadar set
includes a central unit with a Notebook-type computer**
mounted on a special platform, a set of antennas for
various sounding frequencies, software, various
accessories (see Specifications). Note: New shielded 300, 500 and 900 MMHz are shown below. |
**As a rule, a Notebook-type computer is not included in a standard supply. Users may use their own computers for cost saving purposes. Still, computer may be included in the supply on a specific request and at an additional charge.

Antennas are made dust/sprayproof and may be even immersed in water for a short time. Surface antennas have vinilplastic substrates with extremely high abrasion resistance. Till now, we haven't received from our customers any requests for substrate replacement.
All georadar parameters are computer controlled, therefore many hardware operation features are described in sec. Software.
Use of a specific antenna is determined by a sounding task. Higher sounding frequency means better resolution, but with more significant electromagnetic wave attenuation in the environment, resulting in lower sounding depth; and vice versa - lower frequency may lead to a larger penetration depth at the sacrifice of poorer resolution. Moreover, lower frequency produces larger initial insensitivity area ("blind" zone) of a georadar.
A table below shows relationship between resolution, "blind" zone and sounding depth with reference to the antenna used. It is assumed that sounding is made in a soil whose relative dielectric permittivity is equal to 4 and specific attenuation is 1 to 2 dB/m. Depth of investigation is understood to be detection depth of a flat boundary with reflectance equal to 1. Note that these data are rather approximate and are strongly dependent on parameters of the environment sounded.
