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 ...
Microwave Radiometer (MWR) is an instrument on the Juno orbiter sent to planet Jupiter. [2] MWR is a multi-wavelength microwave radiometer for making observations of Jupiter's deep atmosphere. [3] MWR can observe radiation from 1.37 to 50 cm in wavelength, from 600 MHz to 22 GHz in frequencies.
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.
Microwave Imaging Radiometer with Aperture Synthesis (MIRAS) is the major instrument on the Soil Moisture and Ocean Salinity satellite (SMOS). MIRAS employs a planar antenna composed of a central body (the so-called hub) and three telescoping, deployable arms, in total 69 receivers on the Unit.
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.
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 Advanced Technology Microwave Sounder (ATMS) is a 22-channel scanning microwave radiometer for observation of the Earth's atmosphere and surface. It is the successor to the Advanced Microwave Sounding Unit (AMSU) on NOAA weather satellites. ATMS units have been flown on the Suomi NPP and on the Joint Polar Satellite System. [1] [2]
The Weather System Follow-on Microwave (WSF-M) satellite is the United States Department of Defense's next-generation operational environmental satellite system. WSF-M will be a Sun-synchronous low Earth orbit (LEO) satellite with a passive microwave imaging radiometer instrument and hosted furnished Energetic Charged Particle (ECP) sensor.
