The SMAP Radio-Frequency Interference (RFI) Working Group (RFIWG) was set up to assist the SMAP project in identifying and understanding sources of radio-frequency interference that could potentially degrade the quality of SMAP radiometer and radar measurements. The RFIWG is also tasked to advise the SMAP project on implementing RFI mitigation steps (both hardware and software) as considered necessary. Although there are RFI issues for both the SMAP radar and radiometer, the focus of the RFIWG at least for the short term will be on the radiometer side as this has the greatest potential impact on the SMAP instrument design. The RFIWG will assess the L-band RFI environment expected to be encountered by SMAP and the "residual RFI" remaining after the SMAP radiometer baseline RFI mitigation (fullband pulse detection at 240 usec time resolution) is applied. Key to development of techniques for radiometer RFI mitigation is the acquisition, analysis and evaluation of datasets from flights of the PALS airborne L-band SMAP simulator. The PALS RFI flight instrumentation includes specialized hardware for analyzing RFI. In addition to the PALS data the RFIWG will also review other airborne and spaceborne L-band datasets that should be considered in this process. The RFIWG will conduct business mainly via email and exchange of documents. A message board and document exchange location have been established to aid in communication. Contact Information
