The geophysical equipment described is designed for subsurface profiling, using a monostatic Ground Penetrating Radar (GPR) with a single transceiver antenna based on the Real Time Sampling (RTS) technique. This equipment can be manually transported or moved using transportation, with a speed limit of 20 km/h.

The primary goal is to obtain continuous profiles of the subsurface structure along the survey line. Its applications include bedrock surface mapping, glaciology, shallow geology, cavities detection, water table mapping in sand deposits, mapping of pond and river bottoms and their deposits, river paleobeds, industrial waste mapping, and thawed zones in permafrost.

The RTS technology digitizes analog signals on the antenna side and connects the analog-to-digital converter directly to the dipoles of the receiving antenna, significantly increasing the clocking speed and expanding the dynamic range. This also enhances the GPR's moving speed and improves the signal-to-noise ratio through high digital signals traffic and high stacking.

Data processing is done using Prism2 software, which transmits data in real-time to a computer via Wi-Fi and stores the received data in SEG-Y format.
