Abstract

The analysis of scattering characteristics of reference reflectors buried in the ground is carried out. Bistatic scattering diagrams 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 the disk on its radius and depth of immersion in sand are calculated. The results of a georadara study of the scattering characteristics of a metal disk are described. The algorithm of aperture synthesis and the Hilbert transform in the formation of a radar image of a local object in the near irradiation zone are investigated. A technique for measuring the EPR of a local object using its radar image and external calibration data has been developed. The results of measuring the EPR of various cylindrical objects are presented.
