DATABASE OF SMOS RFI SOURCES IN THE 1400-1427MHZ PASSIVE BAND

The European Space Agency's Soil Moisture and Ocean Salinity (SMOS) mission operates in the 1400-1427 MHz frequency band, which is allocated to the EESS (passive) service in the ITU Radio-Regulations. The measurements of SMOS radiometer are perturbed by radio frequency interference (RFI) that jeopardize part of its scientific retrieval in certain areas of the World.The strategies initiated by the European Space Agency to mitigate the impact of RFI includes the detection, monitoring, and reporting of the interference cases. Due to the large number of sources detected, their temporal variability, and the fluid contacts with some National Administrations, it was necessary to automate the RFI mitigation process.This paper presents the database created for the classification of the RFI sources and their details, including a website for queries and reports using the stored data. In addition, the algorithms developed to automate the detections that populate the database are explained.
