Feature-Enhanced SAR Imaging Method Based on Regularization in Image Domain

通过分析SAR成像过程和正则化特征增强方法的特点,提出了一种在图像域进行正则化特征增强的成像方法。实验结果表明,本文方法能较好地抑制旁瓣和噪声,提高SAR图像的对比度,保护目标并提高图像的分辨率,且计算量比传统方法大大减小,有效提高了计算效率。

By analyzing the characters of SAR imaging and feature-enhanced SAR imaging methodbased on regularization. this paper presents the feature-enhanced SAR imaging method based on regulariza-tion in image domain. The experimental results demonstrate that our method can efficiently suppress thesidelobe and noise, improve the contrast of image. protect the targets and improve the resolution of image.Compared with the traditional method, our method improves greatly the computation efficiency.
