Detection of weak signals in noisy environment
Abstract
Detection of weak signals in noisy environment is required for a wide variety of navy applications. In many occasions, signal propagation underwater and in the air will cause corruption and amplitude attenuation due to signal broadening and effects of propagation environment. Both underwater and atmospheric environments could be turbulent and cause signal corruption. Moreover, in many instances, the initial signals to detect are rather weak to start from consequently effects of the environmental noises could be very damaging for detection of such signals. The specific goal of this work is to design and test a nonlinear methodology to identify and detect weak signals embedded in noisy data. UCF will test and apply our approach to (a) detection of weak magnetic signals, (b) detection of weak optical signals underwater for optical communication, and (c) detection of weak acoustic signals underwater for acoustic sensing. UCF will be designing nonlinear algorithms for detection of low amplitude pulses as well as periodic signals coming from acoustic, magnetic, and optical sources.
