general description

GROT 12E is a high-frequency variant of GROT 12 series ground penetrating radars with a frequency range from 50 to 1000 MHz.

GROT 12E consists of a transmitter, a receiver and a set of antennas. The radar is controlled with a personal computer (it can be a netbook or a tablet computer, for example) via Bluetooth, Wi-Fi or a connecting cable. Data processing and interpretation take place in real-time. Control program has a user friendly, convenient interface. Signal registration is carried out directly in a digital linear form.

GROT 12E comes with different antennas with various frequencies ranges available with centre frequencies of 750 MHz - 37 MHz and sizes in the unfolded form of 0.2 - 4 m accordingly. The use of shorter antennas can greatly increase the resolution of the device. For example, a GROT 12E type ground-penetrating radar with 0.2 meters long antennas can distinguish inhomogeneities of about 3 centimetres deep, while the measurement accuracy is determined by the interspace, which is used to move the device on the track. The georadar is operated by one or two persons in manual or automatic modes with adjustable start period of the registration process.

The ground penetrating radar is characterized by a high rate of scanning and a long battery life.

The data acquisition and processing program allows real time combining GPR scanning and GPS data and building three-dimensional images taking into account the relief with an accuracy of the GPS receiver.
