While astronomers have devoted significant effort to finding exopl anets and trying to observe evidence of remote astro-biology\, a parallel exploration involves observation of “technosignatures”\, or radio sign als that originate outside the solar system with characteristics suggestin g an intelligent source.\n\nIn many ways radio SETI is a special class of communications problem in the realm of electrical engineering\, with aspec ts of game theory in the mix. Consider the challenges: the signal is unkno wn\, and may be intentional (a beacon) or unintentional (involving navigat ion or communications). The transmit frequency is unknown. If a limited me ssage is sent\, the modulation will be unknown\, and even if bits are prod uced\, the message must be decoded. Energy or geometry may limit persisten ce\, so only a small fraction of observations in any pointing direction wi ll have a chance at detection. Without knowledge of the signal\, matched f iltering is not possible. Link budgets may force limits on the signal band width (narrowband tones) or time duration (pulse trains).\n\nThis talk wil l introduce the SETI problem and describe the scope of efforts underway in the radio SETI community. Search strategies to maximize detection rate wi ll be described\, and narrowband SETI algorithms will be introduced. In re cent years\, SETI search capabilities have vastly improved with the use of interferometric arrays covering GHz-class bandwidths\, commensal observin g\, and the use of racks of GPU-enhanced servers\, significantly raising t he potential for new discoveries.\n\nSpeaker(s): Kenneth\, Ken\n\nAgenda: \nPresentation and lunch.
