This paper proposed a novel method of three-dimensional (3D) imaging based on orthogonal-track ground-based arc synthetic aperture radar (GB-SAR). In the scheme, the SAR sensor moves along two orthogonal arc tracks successively and two SAR images are obtained. Then spacial information of the two dimensional (2D) SAR images are extracted to reconstruct the 3D distribution of scatterers in the common...
The 3D and bistatic SAR parametric scattering models of canonical scatterers are approximated as the product of azimuthal and elevational 2D scattering models based on analyzing the scattering mechanisms of canonical scatterers in the 3D and bistatic case. After deriving relationship of the angles, the azimuthal and elevational 2D scattering models are substituted by the fundamental planar scattering...
