%X In order to demonstrate the effectiveness of GTD model, usually used to model the target scattering behaviors in optical frequency band, for target resonance band, a new method for the GTD model parameters extraction based on matching pursuits is proposed in this paper. Then, the proposed method and Li?s least-square-fitting scheme are used to analyze the resonance scattering data of a aluminum sphere and the measured ultra-wide band scattering data of a finite-length cylinder through the GTD model, Altes model and extended Altes model. Furthermore, after contrasting the scattering behavior parameters and fitting results, some important conclusions are obtained.
