Ground Penetrating Radar EasyRad GPR is in whole a radar complex which refers to a category of complex multi-purpose technical devices and requires the preliminary training of a user (hereinafter referred to as an operator).
To help the first-time operators we offer a short (1-3 day) introductory course, which includes both theoretical and applied parts. We strongly encourage to get started only after this introductory training.

SURVEY COURSE ON THE GPR
The aim of the course: acquisition of operator knowledge and practical skills in the use of hardware and software for GPR and processing and interpretation of the data.
1. Geoinformation Systems and Technologies. An overview of apparatuses and methods for sensing physical environments.
2. The history of GPR.
3. The sector objectives of the GPR. Integration with other geophysical methods.
4. Two wave method – seismic and GPR. The same kinematic model of the environment: homogeneous-layered environment; a continuous medium; a homogeneous medium with local heterogeneities and their combinations. Physical environment. Types and the passage of Electromagnetic Signals.
5. The GPR – classification and differences. GPR complex. Transmitter. Receiver. Antenna. Power supply. The Control unit (the computer). Software. The Operator-Interpreter.
6. The dynamic range of the signals. Procedural hardware and physiological constraints. Oscilloscope. The amplitude and phase of the signal.
7. Wave methods in Geophysics. Elements of the theory and practice of Spectral Wave Geometry (SWG). Basic compliance and basic formulas. The geometric dimensions of heterogeneities, anomalies, items, frequency, and wavelength `reflected` (forced) vibrations.
8. Frequency bands and Spectrum signals. The Spectrum analyzer.
9. Analog-to-Digital Converter (ADC). Sample, Track. The radargram. Data formats. Digital to analog Converter (DAC). Building a Profile Radargram. Vertical and horizontal resolution. Options for the presentation of data, including 3D.
