POLSAR Data Reader in MATLAB

The POLSAR data reader implemented in MATLAB serves as a highly practical tool for efficient management and analysis of Polarimetric Synthetic Aperture Radar (POLSAR) data. Beyond basic data reading functionality, this toolkit supports comprehensive data processing pipelines and visualization workflows. Users can generate diverse imagery outputs including polarimetric amplitude images, phase images, and amplitude difference images through customizable plotting functions. The implementation incorporates key algorithms for data filtering (such as boxcar or Refined Lee filters), preprocessing routines (like radiometric calibration and speckle reduction), and advanced reconstruction techniques (e.g., eigenvalue decomposition for polarimetric parameters). Core functions include matrix manipulation for covariance/coherency matrices, polarization basis transformations, and feature extraction modules. This integrated solution significantly streamlines POLSAR data handling while maintaining compatibility with standard formats like COSMO-SkyMed, RADARSAT-2, and AIRSAR through modular I/O handlers.
