A complex target reconstruction characterized by canonical scattering objects

This paper presents a three-dimensional (3-D) target reconstruction characterized by its geometric components, i.e. canonical scattering objects. The target is decomposed into some primitive geometries, which are extracted to represent and characterize scattering features. The object parameters are estimated in the frequency domain based on the least square method, and all estimated objects uses the model-based reasoning rules to reconstruct 3-D target. The simulation of a simplified tank model is used to validate the feature extraction and target reconstruction.
