RCS Measurement Method Based on High-Resolution Sparse Turntable Imaging

This paper proposes a method for obtaining scattering distribution of the target through high-resolution turntable imaging and reversely developing its RCScontributions. The method uses a sparse imaging algorithm to extract the scattering distribution of the scene to be imaged and next constructs the total scattered field of the scatterers on the target, finally obtaining the target's RCS contributions after scaling. The experiment results verify that the proposed RCS measurement method has higher accuracy compared with ones based the traditional imaging algorithms.
