Spatially adaptive polarimetric image despeckling using bandelet transform

European Journal of Remote Sensing, 2020
Polarimetric Synthetic Aperture Radar (PolSAR) imaging extended SAR applications by exploring the polarimetric properties of the target scatterers. Similar to SAR images, PolSAR images are prone to multiplicative speckle noise due to its coherent imaging

Polarimetric SAR cross-calibration method based on stable distributed targets

Geo-spatial Information Science
Polarimetric calibration is essential for the pre-processing of Polarimetric Synthetic Aperture Radar (PolSAR) data because it effectively mitigates polarimetric distortions in the measured PolSAR data.
