| 摘 要： | 同其他SAR成象方法相比,CS算法是一种无需任何内插即能补偿距离徙动的新方法,然而,其分辨力不优于傅氏方法.为改善其方位分辨力,本文提出一种CSB算法,该方法不仅能提高成象分辨力,而且仍能保留CS算法 在二维空变相关时不需要内插的优点.

| Abstract: | Compared with other methods, the chirp scaling (CS) algorithm is a novel one for compensating the range migration without any interpolation in SAR imaging. However, its resolution ability can't exceed that of Fourier transformation. To realize the super-resolution ability in the azimuth direction a chirp scaling Burg (CSB) algorithm is proposed in this paper, which can still reserve the advantage of avoiding any interpolation in the process of the two-dimensional space-variant correlation in the CS algorithm. |
