Abstract :
A method is developed for the 3D image reconstruction of synthetic aperture radar based on a tomographic model. In this model, the demodulated radar return signal could be seen as a set of sampled 3D Fourier transform of the reflectivity density of the target, and a 2D image of projection corresponding to reflectivity in the 3D scene can be reconstructed. Besides, a half-quadratic regularization is developed to deal with the complex valued, random-phased nature of the SAR target reflectivity.
