Abstract

Abstract

To link better scattering centers with target structures, a forward method is presented to deduce the component-level 3-D scattering center position of radar target under the mechanisms of single and double scattering based on target geometric model. Under the mechanism of double scattering, the principle and method for determining the ray equivalent position is introduced especially under the situation of strong scattering. As for other weak scattering situations, the equivalent transformation is used to transform the weak scattering situations to the strong one. Finally, this position derivation method is applied to the models of right dihedral angle, obtuse dihedral angle, SLICY and T72 tank to deduce and analyze their component-level scattering center positions. The corresponding simulated or actual SAR images are used for contrast to validate the accuracy of the position derivation method.
