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.

Microwave radiometer model simulation

International Journal of Remote Sensing, 1996
Abstract The relationship between the instrument engineering parameters and the geophysical parameters derived from a multi-frequency microwave radiometer is considered in this paper. A model is described that simulates the performance of this type of instrument and shows how the overall accuracy of the instrument is reflected in the geophysical ...

A Multifrequency Microwave Radiometer

[Proceedings] IGARSS'91 Remote Sensing: Global Monitoring for Earth Management, 2005
A 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.

Validation of QuikSCAT Radiometer rain rates using the TRMM microwave radiometer

IEEE International Geoscience and Remote Sensing Symposium, 2003
The primary mission of the SeaWinds scatterometer on the QuikSCAT satellite is to infer surface wind vector from ocean backscatter measurements. Occasionally the backscatter measurements are contaminated by the presence of rain; therefore a reliable method of identifying rain is needed.

Handheld L-Band Microwave Radiometer

2006 IEEE MicroRad, 2006
Continued support for remote sensing science requires increased awareness of the general public towards the benefits of this important tool. Unfortunately, information about remote sensing instrumentation and techniques remains inaccessible to many higher-educational institutions due to high cost and lack of expertise and other resources.
