A Cross-Estimation Method for Spaceborne Synthetic Aperture Radar Range Antenna Pattern Using Pseudo-Invariant Natural Scenes

A Cross-Estimation Method for Spaceborne Synthetic Aperture Radar Range Antenna Pattern Using Pseudo-Invariant Natural Scenes

The estimation and correction of antenna patterns are essential for ensuring the relative radiometric quality of SAR images. Traditional methods for antenna pattern estimation rely on artificial calibrators or specific stable natural scenes like the Amazon rainforest, which are limited by cost, comp...
