Abstract
Attributed scattering center model can represent both localized and distributed scattering centers with different values of the parameters. But the representation of the distributed scattering centers using this model is limited to uniformly distributed scattering centers, and is not applicable to the directional characteristics of non-uniformly distributed scattering centers. In this paper, the attributed scattering center model is first reviewed. Then, with a SAR image of a non-uniformly distributed scattering center, the 2D Fourier transform on the mathematical representation of the image is implemented to get the scattering model of the non-uniformly distributed scattering center. Finally, a simulation is conducted to validate the correctness of the model.
