Results of the GPR (Ground-penetrating radar) research in the gardens of the Potocki Palace in Radzyń Podlaski and Zamoyski Palace in Klemensów (Poland). The geophysical research took place in the area of previous baroque formal garden (behind the palace) on an area of 4950 m2 (Radzyń Podlaski) and 2730 m2 (Klemensów). The research was carried out using a multi-channel 3D ground-penetrating radar - Stream C by IDS. This is a ground-penetrating radar with 34 measuring antennas (32 recording channels per 1 m width) with a maximum depth range of up to 3 m below ground level. The indicated area was scanned with unit scans every 4 cm, and thanks to the double polarization of the antennas, a longitudinal and transverse scanning effect with a resolution of 4 cm in two directions was achieved. The measurements were positioned using GNSS RTK (Global Navigation Satellite System, Real-Time Kinematic) technology with corrections from the reference network. Horizontal cross-sections, depth cross-sections from VV and HH antenna polarisation, cut every 5 cm.
