Benefits GROT-12

A key advantage of GROT-12 in comparison with previous generations of GPR was the direct digitization of the received signal for a probe pulse in the whole range of operating frequencies without additional operations gating and frequency conversion. Any of these operations lead to significant distortions in digitizing the signal and requires the repeated increase in the number of probe pulses of the transmitter (and their rate of repetition). As a result, significantly reduces the measurement accuracy, the possibility of an effective post-processing and runtime radar.
Ideological features of GROT-12 allows to reduce signal distortion for digitization, to improve the resolving power, greatly simplify the design of GPR, to conduct processing and interpretation in real time on the computer, to diversify the technology of photography by modifying the parameters of the control program without any changes of design. Of course the amount of information within the parameters of modern laptops is not limited. Were taken into account the weaknesses of previous ground penetrating radar, which used a separate unit registrar, and in some cases due to operator error is a loss of information at the time of transfer from the device to your computer. In the Grot-12 loss of data only with your PC.
Constructive solutions used in the development of georadar GROT-12, have substantially reduced weight, size and power consumption. GROT-12 uses a removable battery, rechargeable from a variety of sources, which is especially important and useful in field conditions.
Depending on the objectives of the study can be used various designs of transmitters and portable antennas. Complete with a GROT-12 offers antennae of different ranges with center frequencies from 150 to 15 MHz and the size of the unfolded form of 1 to 10 meters. Compact, easily dismantled antennas allow for shooting in the most inaccessible places.
For GROT-12 transmitters are available with voltage signal from 5 to 15 kV, a pulse power of 1 to 9 MW and different pulse duration. In particular, the Grot-12 complete with a transmitter 9 kW (pulse duration 5 ns) and two-meter antennas 75 MHz implemented a resolution of 10 cm in the range of the first 10 meters, depth-sensing in suburban clays exceeded 130 meters (25 feet of clay loam, 10 meters of Jurassic clays , limestone interbedded with marl).
Program data collection and processing allows real-time to combine GPR surveying with GPS data and build three-dimensional images, taking into account the terrain with an accuracy given by GPS receiver.

The main advantages

Direct registration signal to a digital linear form;
The weight of the reduced three times;
Processing and interpretation of results in real time, user-friendly graphical interface;
High-speed photography and limited battery life.

Georadar can be used, in essence, in geology and building.
In geological applications: for mapping potential raw structures (for example, opal-bearing) and tectonic dislocations; tracking lithologically heterogenous rock of contrasting composition to depths of up to 100 metres; location of local anomaly-forming objects in plan and at depth (brecciation zones, caverns, karst funnels, quarz veins etc.).

In hydrogeological investigations: assessment at depth of water-bearing horizons, mapping of water-permeable and water-resistant horizons, searching for underground water.

In petroleum geology: searching for structural traps of the anticline type, determination at depth of stratified rock types-collectors of petroleum and gas accumulation.

In archeological geology: search for ancient or abandoned subterranean mine workings, evaluation of tailings dumps of mines etc.

In many other applications: construction, ecology, municipal services, criminal/forensic investigations, mine and shell location, searching for buried treasuries, ancient buildings, cavities etc.

The main advantage of GROT-12 in comparison with previous modifications of georadars GROT and LOZA series is a signal quantization in a full frequency range without strobing and comparison.
In GROT-12 considerably decreased signal distortions during quantization; resolving capacity was enhanced. Data processing and interpretation on computer in real time mode considerably simplified construction of the device. It also allowed to vary sounding technology by the data collecting and processing software without changes inside device construction.

Work with the georadar is produced by two or three operators in the manual or automatic regime, with the adjustable period of starting of the registration process. Georadar is controlled by computer, data processing and interpretation are conducted in real time.

Georadar is equipped by changeable resist-loaded dipole antennas with average operating frequency of 25 MHz, 37.5 and 75 MHz. Sizes of antennas are 6.0m, 4.0m and 2.0m accordingly.
Maximal size of antennas in staked state is about 1 meter for antennas of all types. Application of antennas with different lengths from 2 to 10 meters allow to increase sounding depth. In case of need the delivery of transmitter with increased power and longer antennas is possible.

Weight of transmitter is 1.7 kg. Weight of reciever is 1.8 kg.
