Passive microwave radiometry in biomedical studies [PDF]
Drug Discovery Today, 2020 Passive microwave radiometry (MWR) measures natural emissions in the range 1-10GHz from proteins, cells, organs and the whole human body. The intensity of intrinsic emission is determined by biochemical and biophysical processes. The nature of this process is still not very well known.

RFI Mitigation in Microwave Radiometry Using Wavelets [PDF]
Algorithms, 2009 The performance of microwave radiometers can be seriously degraded by the presence of radio-frequency interference (RFI). Spurious signals and harmonics from lower frequency bands, spread-spectrum signals overlapping the “protected” band of operation, or

A Review of RFI Mitigation Techniques in Microwave Radiometry [PDF]
Remote Sensing, 2019 Radio frequency interference (RFI) is a well-known problem in microwave radiometry (MWR). Any undesired signal overlapping the MWR protected frequency bands introduces a bias in the measurements, which can corrupt the retrieved geophysical parameters.

Microwave Radiometry in Remote Sensing [PDF]
12th European Microwave Conference, 1982, 1982 Microwave radiometry has shown its capabilities of observing and monitoring large-scale geophysical observables from space. Examples are sea surface temperature and surface wind over the ocean, sea ice extent, concentration and category and snow cover extent and water content.

Quantum Microwave Radiometry with a Superconducting Qubit [PDF]
Physical Review Letters, 2021 The interaction of photons and coherent quantum systems can be employed to detect electromagnetic radiation with remarkable sensitivity. We introduce a quantum radiometer based on the photon-induced-dephasing process of a superconducting qubit for sensing microwave radiation at the sub-unit-photon level.
