Glacier melt detection at different sites of Greenland ice sheet using dual-polarized Sentinel-1 images

Geo-spatial Information Science
Synectic Aperture Radar (SAR) backscatter coefficient is sensitive to glacier surface physical characteristic changes, including the states of melting and refreezing, but it is also sensitive to incidence angle variation.

A Two-Stream LSTM-Based Backscattering Model at L-Band and S- Band for Dry Soil Surfaces Under Large Roughness Conditions

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
In this article, we report for the first time two radar measurements (Ji Mo 2008 and Min Qin 2009) on natural soil surfaces under large roughness, which were conducted by the China Research Institute of Radiowave Propagation.

Electromagnetic backscattering by corner reflectors [PDF]

The analysis of the backscatter cross section of a dihedral corner reflector, using Geometrical Theory of Diffraction (GTD) and Physical Theory of Diffraction (PTD), is completed in the azimuthal plane, and very good agreement with experimental results ...
