Application of UWB Near-Field Polarimetry to Classification of GPR Targets

Polarimetric properties of the recently developed IRCTR video-impulse radar are analyzed. These properties are used for the Polarimetrie analysis of data acquired over a sand lane containing landmine simulants and clutter. From the measured scattering matrices, the estimated linearity factor and the angle of orientation of different targets are determined as a function of frequency. Focused multi-component images of different targets are formed and analyzed. It is shown that the eigenvalues of the target scattering matrix and multi-component images can be used for the classification of detected targets.
