Polarimetric Scattering by A Finite Dihedral Corner Reflector

In the field of microwave remote sensing, polarimetric synthetic aperture radar (POLSAR) image analysis is one of the most significant and effective imaging techniques since scattering matrix obtained by POLSAR system may provide us detailed three dimensional high resolution target information [1],[2]. It has been reported in Ref.[3] that three-component scattering model, which is based on simple physical scattering mechanism by surface scattering, double-bounce scattering and volume scattering, is successfully applied to decompose mixed scattering components in measured POLSAR data. This technique is very effective to POLSAR decomposition analysis especially for natural distributed target area. Also, four-component scattering model, which consists of the above three scattering components and additional circular polarization contribution, has recently been proposed in Ref.[4] to realize more accurate POLSAR decomposition analysis in urban distributed area.
