Wideband polarimetric radar imaging

Summary form only given. The relationship of the polarization dependence of the corresponding radar cross-section matrices in the frequency domain with that of the target eigen-resonance maps is demonstrated, leading to the concept of polarimetric wavelets, which offers a useful interpretative tool for polarimetric UWB (ultrawideband) target versus clutter discrimination and analysis. Utilizing available sets of multiband continuous wave spectral polarimetric scattering matrix data sets in the (30) 300 MHz to 3 (30) GHz region, the authors demonstrated the relevance of a ´polarimetric extension´ of the UWB impulse radar approach with the specific aim of identifying the important wide-ranging applications of future UWB (non-carrier frequency) polarimetric impulsive radar (POL-RAD) synthetic aperture radar (POL-SAR), and inverse synthetic aperture radar ISAR (POLISAR) systems not only to low-radar cross section-target analysis but even more so to under-burden (foliage/poorly conductive media) penetration for detecting hidden conducting objects (tanks, mines, etc.) in wide area site/environmental security monitoring.<>
