P lease register at https://events.vtools.ieee.org/m/177203.\n\nBrief Summar y of the talk:\n\nThe detection of very weak signals in the presence of ba ckground noise is a challenge of significant\ninterest for many radar\, so nar\, and communications applications. Standard tools such as the Matched\ nFilter perform poorly when the signal-to-noise ratio (SNR) is less than a bout -10 or -20 dB. Therefore\,\nthe detection of these low SNR signals re quires the development of more sophisticated signal processing\ntechniques .\n\nThe chaotic detector is a non-linear detector that is designed to cou ple to a weak signal of a given\nfrequency\, while (in principle) remainin g immune to the background noise. In particular\, the non-linear\nDuffing Equation\, which describes the motion of a damped\, driven harmonic oscill ator\, has proven to be\nexceptionally well-suited to the detection of wea k sinusoidal signals with SNR less than -30 dB.\n\nThis presentation will discuss the design\, performance\, and limitations of multiple implementat ions\nof Duffing detectors.\n\nPlease email syed.tamseel@ieee.org with fur ther questions and see below for the event day instructions:\n\nOn the day of the event:\n\n1. Lunch is served.\n\n2. Parking is available in the pa rking deck next to the GTRI conference center building. Simply pull up in front of the gate and it should lift up.
