An Improved Geometric Calibration Model for Spaceborne SAR Systems With a Case Study of Large-Scale Gaofen-3 Images
Synthetic aperture radar (SAR) image positioning is commonly affected by factors such as platform instability, aging of onboard instruments, and changing observation environments. Thus, geometric calibration is needed to improve the accuracy of image positioning before mapping and application. An im...
