Geographically-spaced Synchronized Signal Detection System (Please click to read pdf presentation.)


Abstract: Radio Frequency Interference (RFI) is a confounding problem in radio SETI, as false positives are introduced into receiver signals. Various methods exist to attempt to excise suspected RFI, with a possibility that true positives are rejected, and that un-excised RFI remain as false positives. Uncertain far side-lobe antenna patterns add to the uncertainty. To ameliorate the RFI problem, a system having geographically-spaced simultaneous and synchronized reception has been implemented. A radio telescope at the Green Bank Observatory in Green Bank, West Virginia has been combined with a radio telescope of the Deep Space Exploration Society, near Haswell, Colorado to implement a spatial filter having a thrice-Moon-distance transmitter rejection. Approximately 135 hours of simultaneous synchronized pulse observations have been captured from November 2017 through February 2019. This presentation describes the problem, observation system, observed results and a proposed hypothesis to be subjected to attempts at refutation through further experimentation and RFI and ETI transmitter signal model development.

Western Conference of the Society of Amateur Radio Astronomers, in Boulder, March 23-24, 2019

The Deep Space Exploration Society will closely participate with this year’s Western Conference of the Society of Amateur Radio Astronomers.  Conference talks will be given on Saturday March 23.  On Sunday March 24 conference participants can travel to visit the DSES radio telescope site in Haswell, CO. A hotel in Eads is available for staying overnight. Registration is open until February 25, 2019. Below is an announcement we received to pass on.
