Feasibility study on application of microwave radiometry to monitor contamination level on insulator materials [PDF]

open access: yes, 2016
This paper introduces a novel method for monitoring contamination levels on high voltage insulators based on microwave radiometry. Present contamination monitoring solutions for high voltage insulators are only effective in predicting flashover risk when

Soil Moisture Active/Passive (SMAP) L-Band Microwave Radiometer Post-Launch Calibration Revisit: Approach and Performance

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
The soil moisture active passive (SMAP) microwave radiometer is a fully-polarimetric L-band radiometer flown on the SMAP satellite in a 6 AM /6 PM sun-synchronous orbit at 685-km altitude.

Microwave radiometry of blackbody radiation [PDF]

open access: yes2016 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]

open access: yesPhysical 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

open access: yesIEEE 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

open access: yesТехнологія 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

open access: yesRemote 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

open access: yesRemote 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

Normality Analysis for RFI Detection in Microwave Radiometry

open access: yesRemote Sensing, 2009
Radio-frequency interference (RFI) present in microwave radiometry measurements leads to erroneous radiometric results. Sources of RFI include spurious signals and harmonics from lower frequency bands, spread-spectrum signals overlapping the “protected ...
