N2 - The traditional synthetic aperture radar (SAR) is an active acquisition instrument that generates radiation and captures signals backscattered from the illuminated scene. However, when the phases of each reflection path are highly similar, the received echoes may sum in a destructive way. In this way, only a few strong scattered points of targets can be preserved in the traditional images. To recover the disappeared geometric features of the targets in SAR images, this paper proposes a parametric imaging method for circular-plate targets. Through analyzing the scattering models of various targets, the scattering feature of the circular-plate target in image domain is first presented. And by identifying the target type in image domain, the geometry information lost in the traditional image is recovered based on the scattering models. Numerical simulations have been conducted to demonstrate the effectiveness of the proposed method.
