Microwave radiometry of blackbody radiation [PDF]
2016 Conference on Precision Electromagnetic Measurements (CPEM 2016), 2016 We outline the theoretical formulation of radiometry of the free-space radiation emitted by a blackbody target. Simulation shows a much smaller drop of radiation intensity of a Lambertian source than that of an incoherent source in the near-field region, indicative of a powerful influence produced by the coherence property of the blackbody source ...

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.

A Snowfall Detection Algorithm for ATMS Over Ocean, Sea Ice, and Coast
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022 This study developed a snowfall detection algorithm over ocean, sea ice, and coast for the advanced technology microwave sounder (ATMS) onboard both NPP and NOAA-20 satellites. The detection algorithm was trained from collocated observations between ATMS-

Designing medical devices for non-invasive diagnostics using microwave radiometry
Технологія та конструювання в електронній апаратурі, 2023 Temperature is often used among the information required to diagnose the state of a person’s internal organs, as pathological processes occurring in the human body are usually accompanied by thermal deviations not only on the surface but also inside the ...

Physical Retrieval of Rain Rate from Ground-Based Microwave Radiometry
Remote Sensing, 2021 Because of its clear physical meaning, physical methods are more often used for space-borne microwave radiometers to retrieve the rain rate, but they are rarely used for ground-based microwave radiometers that are very sensitive to rainfall.

The Challenges of Remotely Measuring Oil Slick Thickness
Remote Sensing, 2018 The thickness of oil spills on the sea is an important but poorly studied topic. Means to measure slick thickness are reviewed. More than 30 concepts are summarized. Many of these are judged not to be viable for a variety of scientific reasons. Two means
