Due to the long aperture, the high-resolution imaging for strip-map SAR with missing data is a challenge, in which the range migration correction and phase error correction are challenging. In this paper, a high-resolution imaging method of this type

With the circular-scanning mode, we can obtain real-time synthetic aperture radar (SAR) images of wide areas including both sides of the nadir line, which considerably benefits the terrain matching procedure. However, due to the continuous rotation o

It is possible to obtain real-time images of broad regions, including the both sides under flight path, for image-matching by using the circular-scanning synthetic aperture radar (SAR). However, due to the continuous rotation of the antenna beam, the

With the development of spaceborne synthetic aperture radar (SAR), the high resolution has become a hot topic again in recent years. However, the higher the resolution is, the worse the accuracy of the traditional hyperbolic range model (HRM) gets. I
