DIFFERENTIAL REFLECTOMETRY

Le Journal de Physique Colloques, 1983
The advantages of spectroscopic ellipsometry and spectral reflectivity are combined in differential reflectometry, in which the normalized difference between the reflectivities of two specimens is measured as a function of photon energy. The main advantage of DR lies in its ability to eliminate any undesirable influences of oxides, windows ...

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.

Estimating Backward Scattering Using GNSS-Reflectometry Measurements for Soil Moisture Retrieval

IEEE Access
Soil Moisture (SM) is a key geophysical variable that enables a better understanding of the Earth’s hydrological processes. Missions like Soil Moisture Ocean Salinity (SMOS) and Soil Moisture Active Passive (SMAP) have been the primary sources of ...
