Wide-area (i.e., wide-swath, which means a large imaging swath in elevation) and staring (persistently remote observing) synthetic aperture radar (SAR) imaging is of great utility in microwave remote sensing; however, it cannot be efficiently achieved for current spaceborne and airborne single-antenna SAR systems due to the minimum antenna area constraint [1], [2]. Spaceborne SAR has an imaging capability with a wide area but with a limited azimuth resolution. In contrast, airborne SAR has an imaging capability with a high resolution but with limited swath coverage. Moreover, neither spaceborne nor airborne SARs provide staring imaging. There is therefore a clear incentive to increase the swath width and azimuth resolution simultaneously.
