sky survey sensitivity to narrow band signals we are working on upgrading the spectral resolution of the SERENDIP VI spectrometer to  1 Hz channelization.

We also plan to continue improving our RFI mitigation and candidate selection post processing algorithms, which will benefit several other SETI sky surveys as well (SERENDIP6 sky surveys at Arecibo and Green Bank, and the SETI@home multi-beam sky survey at Arecibo).The main purpose of our program is to search for extraterrestrial civilizations, but the project is also helpful to study the RFI environment around FAST.

We have begun working on real-time RFI rejection and first level identification of potential candidate signals, which would trigger a 100 second raw voltage dump of time domain data on all 38 signals from the the multibeam receiver (19 beams and two polarizations) for subsequent off-line analysis. This time domain data would allow us to cross correlate beams, thereby reducing source position uncertainty, as well as provide more robust RFI mitigation.

We are also considering continuously recording raw time domain data streams from all 38 signal chains on the FAST multi-beam receiver, which will allow us to send out the data to SETI@home volunteers for a more thorough and sensitive analysis.
