Abstract Parameter estimation of radar target scatterer plays an important role in the process of target characteristics analysis and target recognition. Based on the GTD(Geometrical Theory of Diffraction) parametric model, this paper presents a novel method which can synthetically apply the multi-band measurements in frequency domain and effectively estimate the parameters of scatterers, including location, amplitude and scattering type. The numeric results indicate that the method can effectively mine the information hidden in the model and hold the ability of supper-resolution, which provides a new way to ultra-wide-band signal processing of radar.
