LuTan-1: First Demonstration of Hybrid-Polarimetric Synthetic Aperture Radar—Assessing Application Potentials and Performance Constraints

Journal of Remote Sensing
The hybrid-polarimetric (HP) mode is an emerging synthetic aperture radar polarimetric mode that offers a wider swath and improved range ambiguity performance compared to the quadrature-polarimetric (QP) mode, with a slight loss of polarimetric ...

An Improved H/ $\alpha$ Unsupervised Classification Method for Circular PolSAR Images

IEEE Access, 2018
In conventional polarimetric synthetic aperture radar, targets are usually assumed isotropic, and potential polarimetric variations in azimuth are ignored.
