A microwave radiometer consists of an antenna system, microwave radio-frequency components (front-end) and a back-end for signal processing at intermediate frequencies. The key element is the Dicke switch, which alternately switches between the antenna and a cryogenic load at a known temperature.

On these spacecraft, AMSU-B is replaced by similar microwave humidity sounders: HSB for Aqua and MHS for MetOp. The AMSU was an improvement of the Microwave Sounding Unit (MSU), incorporating capabilities of the Stratospheric Sounding Unit (SSU), both of which had flown on TIROS -N in 1978 and continued on the NOAA-6 through NOAA-14 satellites.
Putting a non-microwave-safe material in a microwave oven can lead to chemicals leaching into your food (not good) or the melting of the container, which can lead to burns — or, at the very ...
A microwave oven or simply microwave is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. [1] This induces polar molecules in the food to rotate and produce thermal energy in a process known as dielectric heating .
Beamforming or spatial filtering is a signal processing technique used in sensor arrays for directional signal transmission or reception. [1] This is achieved by combining elements in an antenna array in such a way that signals at particular angles experience constructive interference while others experience destructive interference.

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.
