Modified Orbit Algorithm with Sparse Ground Control Points for Geo\|rectification of Space\|borne SAR Image

    Graphical Abstract
    • Abstract
  • A modified orbit algorithm with sparse ground control points (only three points for high accuracy geo\|rectification of space\|borne SAR image is proposed, which is based on range\|doppler position model and high precision orbit ata of GPS. The algorithm decreases the number of ground control points through simplifying the orbit parameter odel, so it can improve the work efficiency on the basic of high accuracy correction.
