RFI Mitigation in Microwave Radiometry Using Wavelets
The performance of microwave radiometers can be seriously degraded by the presence of radio-frequency interference (RFI). Spurious signals and harmonics from lower frequency bands, spread-spectrum signals overlapping the “protected” band of operation, or out-of-band emissions not properly rejected by the pre-detection filters due to the finite rejection modify the detected power and the estimat...
متن کاملNormality Analysis for RFI Detection in Microwave Radiometry
Radio-frequency interference (RFI) present in microwave radiometry measurements leads to erroneous radiometric results. Sources of RFI include spurious signals and harmonics from lower frequency bands, spread-spectrum signals overlapping the “protected” band of operation, or out-of-band emissions not properly rejected by the pre-detection filters due to its finite rejection. The presence of RFI...
متن کاملRFI Mitigation/Excision techniques
Radio frequency interference (RFI) is increasingly affecting radio astronomy research. A few years ago, active research to investigate the possibility of observing in the presence of interference using RFI mitigation techniques was initiated. In this paper, I briefly discuss four RFI mitigation/excision projects. These projects are: (1) A technique to suppress double sideband amplitude modulate...
متن کاملRFI Mitigation for Pulsar Observations
An adaptive filter for RFI mitigation has been brought on-line at the Parkes observatory, embedded in the most recent pulsar observing system. The filter meets the design criteria, and provides substantial RFI mitigation. This note describes the filter and some recent field trials.
متن کاملEnhancing Oceanic Retrievals using Microwave Radiometry
The Central Florida Remote Sensing Laboratory, CFRSL, of the School of Electrical Engineering and Computer Science at the University of Central Florida is engaged in research to improve passive microwave remote sensing techniques for inferring oceanic and atmospheric geophysical parameters. This paper presents an overview of research that falls into three major areas, namely; airborne hurricane...
