Abstract :
The presence of anthropogenic RFI is expected to adversely impact soil moisture measurement by NASA´s Soil Moisture Active Passive mission. The digital signal processing approach and preliminary design for detecting and mitigating this RFI is presented in this paper. This approach is largely based upon the work of Johnson and Ruf.
