Array-Fed Microwave Radiometer

2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021
Modern 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 ...

Detecting RFI using microwave radiometers

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
Generally 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.

Microwave Photonic Imaging Radiometer

2018 IEEE 15th Specialist Meeting on Microwave Radiometry and Remote Sensing of the Environment (MicroRad), 2018
Nano-satellites are gaining in popularity due to their low cost and ease of deployment. Reaching orbit as secondary payload to larger spacecraft enables science grade missions at disruptively low cost. Such miniaturized platforms impose severe constraints on the size, weight, and power (SWaP) of the payload, however, making large antenna apertures ...

Dual Frequency Microwave Radiometer

12th Canadian Symposium on Remote Sensing Geoscience and Remote Sensing Symposium,, 2005
A dual-frequency microwave radiometer has been developed to remotely sense water vapor and liquid in the troposphere. An optimum frequency pair, 20.60 and 31.65 GHz, is adopted. The system consists of two Dicke radiometers (one at each frequency), both of which are controlled by a microcomputer system and mounted on a rotatable pedestal.
