Characterizing Bandlimited Nonlinear (and Linear) Systems with Memory while Reducing the Curse of Dimensionality using a new Volterra Expansion Technique
October 17, 2017 @ 6:00 pm - 9:00 pm
The overarching goal of this research is to provide a new active sonar signal processing method to exploit the nonlinearity inherent in underwater sound channels. This new approach aims to enhance detection, classification, and localization (DCL) through increased frequency coverage and selection beyond the limits of the transmit bandwidth. One possible technical advantage gained from this nonlinear characterization is in mono-static and multi-static sonar. The Navy has always desired multi-static sonar capabilities within shallow water and littoral regions for underwater connectivity. Thus, any new capabilities gained within shallow water are desired since communication and tactical awareness are troublesome in high-reverberation environments. Thus, the proposed signal-processing technique obtains information not traditionally utilized in DCL, which could improve undersea sonar systems like submarines, torpedoes, and sonobuoys.
