While astronomers have devoted significant effort to finding exoplanets and trying to observe evidence of remote astro-biology\ , a parallel exploration involves observation of “technosignatures”\, or radio signals that originate outside the solar system with characterist ics suggesting an intelligent source.\n\nIn many ways radio SETI is a spec ial class of communications problem in the realm of electrical engineering \, with aspects of game theory in the mix. Consider the challenges: the si gnal is unknown\, and may be intentional (a beacon) or unintentional (invo lving navigation or communications). The transmit frequency is unknown. If a limited message is sent\, the modulation will be unknown\, and even if bits are produced\, the message must be decoded. Energy or geometry may li mit persistence\, so only a small fraction of observations in any pointing direction will have a chance at detection. Without knowledge of the signa l\, matched filtering is not possible. Link budgets may force limits on th e signal bandwidth (narrowband tones) or time duration (pulse trains).\n\n This talk will introduce the SETI problem and describe the scope of effort s underway in the radio SETI community. Search strategies to maximize dete ction rate will be described\, and narrowband SETI algorithms will be intr oduced. In recent years\, SETI search capabilities have vastly improved wi th the use of interferometric arrays covering GHz-class bandwidths\, comme nsal observing\, and the use of racks of GPU-enhanced servers\, significan tly raising the potential for new discoveries.\n\nSpeaker(s): Kenneth Hous ton \n\nAgenda: \nEvent Agenda\n\n1.
