Abstract

Conventional Far-field decomposition of the scattered electromagnetic (EM) field in the [EH] plane in terms of the horizontal and vertical components (i.e., h, v), introduces ambiguity for multi-static, multi-platform and/or scene-centric polarimetric synthetic aperture radar (SAR) image exploitation. This is due to the fact that a 2-dimensional (2D) vector field can not constitute a complete space capable of modeling 3-dimensional (3D) field transformations. To address this, extension of the Stokes vector, target scattering vectors and coherency parameters' analytic descriptions to 3D is explored and presented. The results are also applicable to compact polarimetry (CP) where mathematically consistent 3D Stokes parameters can be defined.
