Abstract

Radio frequency interference (RFI) is a well-known problem in microwave radiometry (MWR). Any undesired signal overlapping the MWR protected frequency bands introduces a bias in the measurements, which can corrupt the retrieved geophysical parameters. This paper presents a literature review of RFI detection and mitigation techniques for microwave radiometry from space. The reviewed techniques are divided between real aperture and aperture synthesis. A discussion and assessment of the application of RFI mitigation techniques is presented for each type of radiometer.
Keywords: radio frequency interference (RFI) detection; RFI mitigation; microwave radiometers; time domain; frequency domain; statistical methods; polarimetry; real aperture radiometer; synthetic aperture radiometer radio frequency interference (RFI) detection; RFI mitigation; microwave radiometers; time domain; frequency domain; statistical methods; polarimetry; real aperture radiometer; synthetic aperture radiometer
