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.

Antenna systems for microwave radiometers

Nanotechnology : the development , application - XXI Century
The paper provides an overview of the antenna systems used for microwave radiometers. Due to the development of precision agriculture, the use of radiometers for monitoring soil moisture relief is becoming relevant. Microminiaturization of antenna systems expands the possibility of using radiometers using unmanned aerial vehicles and ground-based ...

TRMM microwave radiometer algorithms

Proceedings of IGARSS '93 - IEEE International Geoscience and Remote Sensing Symposium, 2002
The TRMM Microwave Imager (TMI) is a modified SSM/I. Significant modifications include: the addition of 2 channels at 10.7 GHz (H and V polarization), a shift of the 22.235 GHz V channel to 21.4 GHz H, and increasing the cone angle from 45/spl deg/ to 49/spl deg/.

Temperature resolution of microwave radiometers

Radiophysics and Quantum Electronics, 1997
We consider the quantum limits of the radiometer sensitivity in power and spectral density measurements of the radio emission. It is shown that taking into account zero-point field fluctuations makes it possible to resolve some paradoxes in the theory of an ideal radiometer.
