Imaging of rotation-symmetric space targets based on electromagnetic modeling

摘要

This paper derives the signal model for high-resolution radar imaging of two canonical rotation-symmetric targets in space, i.e., the smooth cone and the smooth cylinder, according to their electromagnetic (EM) modeling in the high-frequency regime and their specific rotation motion. Then, a method based on the complex generalized Radon transform is proposed for image formation and motion parameter estimation. Imaging results of dynamic EM echoes have proved the validity of the proposed method.
