Using the property that the electrically large target at high frequencies has the simple electromagnetic scattering mechanism under the low-resolution radar with narrow bandwidth and small aspect angle sector, this paper performs the parametric modeling of a 2-D SAR target through high-resolution extraction of the scattering center attributes of the target via spectral estimation. To overcome the restriction of high SNR threshold to high-resolution SAR imaging, this paper enhances the signal feature spectrum via the fourth-order cumulant. The feasibility of the method is verified by simulation experiments.
