Advanced microwave precipitation radiometer

[Conference Digest] International Conference on Millimeter Wave and Far-Infrared Technology: ICMWFT '90, 2005
This paper describes the development and preliminary testing of an imaging passive microwave radiometer operating in the 10 to 85 GHz range specifically for precipitation retrieval and mesoscale storm system studies from a high altitude ER-2 aircraft. The instument is referred to as the Advanced Microwave Precipitation Radiometer (AMPR).

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 ...

High Stability Microwave Radiometer

2018 19th International Conference of Young Specialists on Micro/Nanotechnologies and Electron Devices (EDM), 2018
The paper describes a new approach to the design of high stability microwave radiometer based on zero measurement method. The block diagram and operation algorithm of radiometer servo feedback are shown. Mathematical expressions for the evaluation of radiometric resolution and transfer characteristics are also presented.

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.

Microwave radiometer spatial resolution enhancement

IEEE Transactions on Geoscience and Remote Sensing, 2005
Scanning radiometer data processing can allow enhancing the limited intrinsic spatial resolution. This is important for data fusion. Mathematically, the problem to be solved is an inverse ill-posed problem. In this paper we compare the classical Backus-Gilbert inversion method with the truncated singular value decomposition (TSVD) one.

Reflection-free microwave radiometer

IEEE Transactions on Instrumentation and Measurement, 1993
A new microwave radiometer is proposed to make it possible to compare a noise source independently of its reflection coefficient. It is a modification of a correlation radiometer with a 3-dB, quadrature (90 degrees ) hybrid coupler instead of a 180 degrees one as the input hybrid junction followed by a noise injection circuit for realizing temperature ...

Airborne microwave rain-scatterometer /radiometer

International Journal of Remote Sensing, 1982
Abstract An airborne microwave rain-scatterometer/radiometer system operated at 10 and 34-45 GHz was developed for the remote sensing of precipitation, especially rain, from an aeroplane. Airborne rain-scatterometers were developed as a first step for the development of the future spaceborne rain-scatterometer.
