%X Ground Penetrating Radar (GPR) is an effective geophysical method for shallow subsurface structure exploration. The GPR system used in this study operates at a center frequency of 100 MHz with a sampling time window set to 100 ns. Based on the GPS data recorded in the radar measurements, a survey route map for the ground-based polarimetric GPR was generated. Through a data processing workflow that includes background removal, gain adjustment, and band-pass filtering, signals from the landslide surface were obtained at locations consistent with those surveyed by the drone-based GPR. The results reveal the presence of two distinct loess layers within a few meters below the experimental site: the loess above 1.5 m depth is relatively heterogeneous, exhibiting strong volumetric scattering of electromagnetic waves, whereas the loess below 1.5 m is more uniform with almost no internal structure. This dataset is suitable for applications such as identifying subsurface geological structures of loess landslides and assessing subsurface medium properties, providing essential data support for comprehensive research on loess landslides in the Yuzhong area of Lanzhou.
