Case Study:
Data Image:
Results interpretation: The blue‑marked interface corresponds to the ground‑surface reflection, while the red‑marked interface represents the concrete pavement layer. The space between these two interfaces corresponds to the thickness of the first layer. According to the software analysis, the layer thickness is generally around 17–19 cm and relatively uniform. As the dielectric constant was not calibrated on site, a small margin of error remains. No reflections were observed at greater depths; within a testing depth of 0.8 m, the first concrete layer is clearly visible.
