Abstract:
In this paper, different methods are proposed for the detection and mitigation of the undesirable effects of radio-frequency interference (RFI) in microwave radiometry. The first of these makes use of kurtosis to detect the presence of non-Gaussian signals, whereas the second imposes a threshold on the standard deviation of brightness temperatures in order to distinguish natural-emission variations from RFI. Finally, the third approach is based on the use of a threshold applied to the third and fourth Stokes parameters. All these methods have been applied and tested, with the cooperative airborne radiometer for ocean and land studies radiometer operating in the L-band, on the data acquired during airborne campaigns made in the spring of 2009 over the southwest of France. The performance of each approach, or of two combined approaches, is analyzed with our database. We thus show that the kurtosis method is well suited to detect pulsed RFI, whereas the method based on the second moment of brightness temperatures seems to be better suited to detect continuous-wave RFI in airborne brightness-temperature measurements.

Between 2000 and 2003, he was with the Institut National de Recherche Agronomique (INRA), Avignon, France, and with INRA, Bordeaux, France, on the vegetation effects on the radiometric signal in the framework of the SMOS project. In 2004 he was a Postdoctoral Researcher with the Centre d'Applications et de Recherches en Télédétection (CARTEL) Laboratory, Université de Sherbrooke, Sherbrooke, QC, Canada, and worked on the estimation of snow-water equivalent using satellite measurements of surface microwave emission. Since 2007, he has been with the Laboratory ATmosphere, Milieu and Spatial Observations, Guyancourt, France, on airborne brightness temperature measurements of surface. His interest includes surface-parameter estimation using passive and radar microwave remote sensing, mainly in the context of hydrology.
