Optimization of Random Surface Scattering Models for RR Polarization in SoOp-R/GNSS-R Applications

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Polarization in global navigation satellite system-reflectometry (GNSS-R) or signal of opportunity-reflectometry (SoOP-R) is commonly used for retrieving geophysical parameters.

Spaceborne Receiver Design For Scatterometric GNSS Reflectometry.

, 2012
Global Navigation Satellite System-Reflectometry (GNSS-R) is an innovative technique for remote sensing. It uses reflected signals from the navigation constellations to determine properties of the Earth’s surface. The primary focus of this work is the remote sensing of the ocean by measurement of surface roughness.

An Instrument Error Correlation Model for Global Navigation Satellite System Reflectometry

Remote Sensing
All sensing systems have some inherent error. Often, these errors are systematic, and observations taken within a similar region of space and time can have correlated error structure.
