Abstract	In this paper, an innovative imaging concept of STARing Digital Multiple Beam Synthetic Aperture Radar (SAR) is presented for overcoming the shortcoming of traditional SAR in high-resolution wide-swath imaging, which is the combination of the digital beam-forming (DBF) technology with the principle of SAR. The new imaging concept in this paper can avoid the restriction in the traditional SAR, by dividing the imaging area into several sub-patches to imaging independently. In additional, the whole elements in antenna is employed to form multiple beams in receiver with high gain by DBF, and all of them are assigned to achieving the imaging of every sub-patch by staring observation. The staring observation can extend the length of synthetic aperture and improve the azimuth resolution. At last, the mosaicking process is employed to obtain the high resolution width swath imaging. The simulation shows the STARing Digital Multi-Beam SAR can break though the limitation in the tradition SAR effectively, and have the good system performance.
