Currently, the market of subsurface probing devices widely presents ground penetrating radars of various manufacturers, there are classic stroboscopic ground penetrating radars, there are deep pulse ground penetrating radars [1, 2]. One of the reasons for the limited distribution of ground penetrating radars is the high cost of professional geophysical equipment. A group of IZMIRAN employees has developed and is testing the Sphere ground penetrating radar based on a USB oscilloscope attachment [3]. It is intended for prospecting work by novice specialists, students and other interested persons. The ground penetrating radar allows obtaining subsurface radar data and can be used for various surveys. The results of experimental measurements of the Sfera ground penetrating radar are presented. It was also used as a recorder in experiments with a transmitter with pulse amplitudes from 5 to 100 kV, with various types of antennas [4]. A number of experiments were conducted with various antennas using the Sphere ground penetrating radar receiver as a recorder. The results of experiments with multi-vibrator resistively loaded dipole antennas are presented, allowing to increase the dynamic potential and depth of measurements of ground penetrating radars [5]. It was also used for profiling one section of the western shore of Lake Baikal in the area of ​​the Listvyanka near the Irkutsk region on ice, for works on comparison of characteristics of different radars. Inferior in reliability in comparison with professional ground penetrating radars, the ground penetrating radar "Sphere" allows to conduct initial familiarization with the technology of deep ground penetrating radar. It is intended for students of educational institutions for familiarization and subsequent wide implementation for use of geophysical research.
