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.

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021 Ice concentration estimates are typically acquired from algorithms using passive microwave satellite data, and from image analysis charts, but these have limitations. Estimates acquired from passive microwave data have coarse spatial resolution, may have
