Abstract
A procedure is proposed to reconstruct the radar cross section (RCS) of interested targets from synthetic aperture radar (SAR) images. Key factors in imaging are considered for exact RCS reconstruction, including image defocusing from target motion, system over-sampling, window function, zero-padding and image calibration. Experimental results for both numerically calculated inverse SAR (ISAR) and spaceborne SAR image demonstrate the effectiveness and accuracy of the proposed technique.
