A microwave radiometer (MWR) is a radiometer that measures energy emitted at one millimeter-to-metre wavelengths (frequencies of 0.3–300 GHz) known as microwaves. Microwave radiometers are very sensitive receivers designed to measure thermally-emitted electromagnetic radiation. They are usually equipped with multiple receiving channels to ...
"Spaceborne radar altimeters have proven to be superb tools for mapping ocean-surface topography, the hills and valleys of the sea surface. These instruments send a microwave pulse to the ocean's surface and time how long it takes to return. A microwave radiometer corrects any delay that may be caused by water vapor in the atmosphere.
Originally a Dual-channel Radiometers for Earth and Atmosphere Monitoring (DREAM) microwave radiometer was intended as the principal payload of STSat-2A for an expected launch in 2007. [6] The Laser Retroreflector Array (LRA) was described as an early expected payload for STSat-2A which would consist of nine retroreflectors in a mechanical casing.
The Special Sensor Microwave/Imager (SSM/I) is a seven-channel, four-frequency, linearly polarized passive microwave radiometer system. [1] It is flown on board the United States Air Force Defense Meteorological Satellite Program (DMSP) Block 5D-2 satellites.
The electrically scanning microwave radiometer (ESMR) was an instrument carried by the Nimbus 5 and Nimbus 6 satellites, precursor to the scanning multichannel microwave radiometer (SMMR) and special sensor microwave/imager (SSM/I) instruments.
Las Vegas Raiders quarterback Gardner Minshew II sustained a season-ending broken collarbone in Sunday's 29-19 loss to the Denver Broncos, coach Antonio Pierce confirmed on Monday.. The injury ...
