Abstract. The analysis of the effective scattering surface (ESR) of reference reflectors buried in the ground is carried out. Diagrams of angular scattering of metal spheres with a small ratio of the length of the irradiating field and the radius of the sphere are given. The dependences of the EPR of metal disks on the depth of immersion in the near irradiation zone are calculated. Radar images of a metal disk buried in sand are given. The analysis of the effect of the aperture synthesis algorithm and the Hilbert transform on the formation of the output signal of the receiving path of the georadar is carried out. A technique for measuring the EPR of a local object has been developed, using measurements of the depth of immersion, the signal level at the output of the receiving path and external calibration data. The results of measuring the EPR of cylindrical objects are presented.
Key words: effective scattering surface, external calibration, reference reflectors, aperture synthesis, Hilbert transform.
