Radar target-ground interaction

An investigation of the X-band (∼10GHz) Electro-Magnetic (EM) scattering of a complex vehicle in-situ is reported. The aim of this work is to characterise radar multi-path effects in Synthetic Aperture Radar (SAR) imagery, and further to demonstrate how an appropriate choice of polarimetric basis can allow its mitigation. Ground-target multi-path effects reduce the interpretability of imagery by adding artefacts. Additionally, multi-path impacts on Automatic Target Recognition (ATR), because for any given situation it will not be clear what kind of ground should be employed for the training database.
