Microwave Radiation

, 2015
Microwave radiation is a form of electromagnetic radiation. It covers, broadly speaking, frequencies between 300 MHz and 300 GHz. For example a microwave oven operates at a frequency of 2.45 GHz and many mobile network providers use frequencies between ...

Methods of research of radiothermal radiation of cryospheric objects in the microwave range [PDF]

E3S Web of Conferences
Many cryospheric formations on Earth have an inaccessible location. For example, when studying ice sheets located on the water surface, at the initial moment of ice formation, it becomes difficult to take samples.

An Evaluation of the Applicability of a Microwave Radiometer Under Different Weather Conditions at the Southern Edge of the Taklimakan Desert

Remote Sensing
As an important means to monitor atmospheric vertical temperature and humidity, the ground-based microwave radiometer has been widely used in environmental monitoring, climate prediction, and other fields, but its application in desert areas is ...

Mapping of Acoustic Noise and Microwave Radiation

Cybernetics and Information Technologies, 2016
Passive sensor systems are attractive for monitoring due to the absence of probing emissions. Two passive systems: an acoustic camera, manufactured by Brüel & Kjær (Sound and Vibration Measurement A/S) and a microwave radiometer are considered in the ...

Measuring ice accretion with a microwave radiometer. [PDF]

, 2017
Ice accretion inside jet engines is a major threat to modern aviation. Ice crystals in the atmosphere can be ingested by turbofan jet engines and build up inside reducing airflow through the engine.
