Soil Moisture and Ocean Salinity, European Space Agency, is the first satellite mission
addressing the challenge of measuring sea surface salinity from space. It uses an L-band …

This paper gives an overview of measurement techniques used in the THz region of the
electromagnetic spectrum, from about 100 GHz to several THz. Currently available …

The Soil Moisture and Ocean Salinity (SMOS) mission carries the Microwave Imaging
Radiometer using Aperture Synthesis (MIRAS) instrument. It is the first time that an …

Water pollution caused by anthropogenic activities and driven by changes in rural livelihood
strategies in an agricultural system has received increasing attention in recent decades. To …

The Earth's magnetic field induces Zeeman splitting of the magnetic dipole transitions of
molecular oxygen in the atmosphere, which produces polarized emission in the millimeter …

This manuscript first revises the performance of total power, Dicke-type and noise-injection
microwave radiometers. Equations for the radiometric resolution are revised or derived, and …

We have presented a close look at effects of order hf/kT in noise measurements and in the
definition of noise quantities-noise temperature, noise figure, etc. Given the perennial push …

This work compares microwave radiometry and global navigation satellite systems-
reflectometry (GNSS-R) observations using data gathered from airborne flights conducted …

This article addresses the further development of the ground-based temperature radiometer
TEMPERA, which measures atmospheric microwave radiation in one linear polarization in …

This work focuses on the relationship between real and synthetic aperture radiometers
giving a general and common mathematical framework for both of them. It will be …
