Currently, ground-penetrating radar (GPR) is often used to solve problems related to searching for and recognizing underground objects. This allows for obtaining rich information about the studied area at various depths, but manual interpretation of radargrams is labor-intensive. This paper proposes the GeoRTr method for automatically detecting underground objects of interest. It is based on an original neural network architecture with a GeoAttention mechanism. The network's input is A-scans from a GPR mounted on a wheeled robot moving in automatic or semi-automatic mode. The proposed neural network model accounts for spatial relationships between A-scans even when the robot's trajectory deviates from a straight line. Using a mobile wheeled robot and a GPR with an antenna mounted at a low altitude above the surface being analyzed, a unique dataset was collected and labeled for recognizing several categories of subsurface objects. Experiments with the developed neural network model on the collected dataset demonstrated a classification F1-score of over 40%, surpassing comparable methods. A comparative analysis of various model architecture variations identified two configurations for different ground-penetrating radar object search conditions.
