Abstract


Slant-Range precision of the space-borne SAR is the one of most important factor for imaging quality, especially for geo-location and azimuth imaging quality. In this paper, In-Orbit joint calibration scheme is proposed and implemented for the first time at home. Material content include: Firstly, the error model of slant-range accuracy is established, and effect factor is analyzed. Secondly, in-orbit joint calibration scheme is researched to upgrading slant-range accuracy. Finally, math analysis is used to ensure the feasibility and validity of the scheme
