摘要：

Traditional synthetic aperture radar (SAR) imaging methods assume that radar targets are composed of point based scattering centers, which is not suitable for wide angle imaging. Moreover, gaps of components may be resulted because of neglecting their inherent scattering behaviors. In this way, it is hard to interpret and identify targets from SAR images. Therefore, a component imaging method for SAR is proposed in this paper, taking into account the inherent behaviors of components of radar targets to enhance the integrity of components in SAR. As a result, the SAR image is more likely to be understood by non-expert. Finally, experimental results based on both simulated and real measured data validate the effectiveness of the proposal. Compared with traditional methods, the proposal has improved the quality of the image both qualitatively and quantitatively. © 2021, Editorial Office of Systems Engineering and Electronics.
