RFI Database Contest
The RFI Database Contest is the first competition organized by the Frequency Allocations in Remote Sensing (FARS) Technical Committee of the IEEE Geoscience and Remote Sensing Society (GRSS). The contest challenges to simulate typical Radio Frequency Interference (RFI) observed in remote sensing satellites.
About the research
In this study, we generated simulation data that reproduces the impact of Radio Frequency Interference (RFI) received by L-band (1.2 GHz) Synthetic Aperture Radar (SAR), originating from communication and navigation systems operating in the same frequency band. We simulated the effect on observation and SAR processing, including polarization information. The work was evaluated based on practicality and reproducibility, and it won the competition.
