Study on the Azimuth Resolution of Spaceborne SAR Working on Spotlight Mode
星载合成孔径雷达聚束模式方位分辨率研究

From the difference of imaging geometry between spaceborne SAR, and airborne SAR, traditional formula computing the azimuth resolution of airborne SAR working on spotlight mode will bring big errors if it is used for spaceborne SAR. In this paper, the new formula of the azimuth resolution for spaceborne spotlight SAR. is presented, and the data simulation results validate the validity of the new method.
