Abstract

In common differential synthetic aperture radar tomography (D-TomoSAR) system, the accuracy of deformation estimation tends to be influenced by temporal decorrelation and the atmospheric delay. The traditional liner model cannot express the real deformation as well. This paper proposes a polynomial deformation model for multi-dimensional reconstruction using bistatic SAR (BiSAR) data. This method combines the improved RELAXation (RELAX) algorithm with fractional fourier transform (FrFT). As a consequence, the parameters of ground elevation, linear and non-linear motion can be estimated properly. Both theoretical analysis and experiment results show that separating different scattering mechanisms within one resolution cell is feasible.
