A RST-Based study of AMSRE C-band radio frequency interferences

Radio Frequency Interference (RFI) is becoming an increasingly severe problem for present and future microwave satellite missions. Transmissions from ground based systems at low microwave frequencies can contaminate, with a high level of noise, the remote sensed measurements (both from aircraft and satellite) at these wavelengths. In this work, the multi-temporal Robust Satellite Techniques (RST) approach has been applied in order to identify land areas where C-band AMSR-E (Advanced Microwave Scanning Radiometer on Earth Observing System) radiances are systematically affected by RFI. A preliminary RFI exclusion map for AMSRE C-band has been developed. Among its possible uses, such a product may help to localize where using AMSR-E for soil moisture retrieval is less practicable because highly RFI. Preliminary results of such an analysis will be shown in this paper, discussing also its possible implementation at higher AMSR-E frequencies as well as on other satellite sensors.
