L-band radiometer for a flexible microwave radiometer payload
, 2017 Nowadays the aerospace industry is doing its next step to a new generation of satellites, simplest, smaller and cheaper. The CubeSats are small satellites formed by cube units of 10x10x10 cm3 and are usually designed to carry devices that have to be tested on space or even scientific payloads.

Microwave Radiometer Systems, Design and Analysis
, 2006 Two important microwave remote sensors are the radar and the radiometer. There have been a number of books written on various aspects of radar, but there have been only a few written on microwave radiometers, especially on subjects of how to design and ...

Array-Fed Microwave Radiometer
2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021Modern multi-band radiometer imagers are designed trading spatial resolution, spectral coverage, and surface sampling characteristics to optimize science return. In this process, trades must be made to usually under-sample the Earth scene. Care is taken to obtain contiguous 3-dB edge-to-edge coverage, but even so, such a design still aliases high ...

An Enhanced Product for the Fsscat Microwave Radiometer
IGARSS 2020 - 2020 IEEE International Geoscience and Remote Sensing Symposium, 2020In this study, an enhanced spatial resolution product is proposed for the forthcoming L-band microwave radiometer operated on board of the FSSCat mission. The product is obtained reconstructing the brightness temperature on a finer spatial resolution grid using an antenna pattern deconvolution method.

Detecting RFI using microwave radiometers
2012 IEEE International Geoscience and Remote Sensing Symposium, 2012Generally the disturbing effect of an unintentionally received electromagnetic signal is called radio frequency interference (RFI). Since microwave radiometers are the most sensitive devices for the detection and monitoring of electromagnetic radiation they are highly susceptible for any interference signal.

A Multifrequency Microwave Radiometer
[Proceedings] IGARSS'91 Remote Sensing: Global Monitoring for Earth Management, 2005A three-frequency microwave radiometer was completed in 1990 in the Laboratory of Space Technology, HUT. The instrumentwas designed to be installed onboard a helicopter. Functional description of the radiometer will be given along with its performance parameters. The radiometer is used for remote sensing of snow, ice and forest.

On the Superresolution of Microwave Scanning Radiometer Measurements
IEEE Geoscience and Remote Sensing Letters, 2008Microwave radiometer measurements are exploited to extract important geophysical information. Although it is beneficial to merge different frequency channels, it requires extra effort to refer all measurements to a common spatial resolution. Therefore, the capability to enhance the spatial resolution of a single channel is of special interest.

Fire Emissivity Detection by a Microwave Radiometer
IEEE Geoscience and Remote Sensing Letters, 2015In this letter, the detectability of fire by a microwave radiometer is investigated. In order to understand the fire from a radiometric point of view, the parameters of fire emissivity had to be determined. Therefore, representative fire types were analyzed, and fire spot emissivity values have been derived from measured data.
