Passive Ocean Sensing using Shipping Sources
Abstract
"Performing blinding deconvolution of shipping sources of opportunity can provide atotally passive means to estimate through-the-sensor the channel impulse response (CIR)between a given shipping vessels location and a receiver array. We hypothesize that thesethrough-the-sensor estimated CIRs can be used for passively sensing dynamic environmentalparameters. To this end, we propose a 3 years research effort to quantify the accuracy ofestimating through-the-sensor CIRs from deconvolution of shipping sources (i.e. moving nonstationaryrandom sources with anisotropic radiation pattern) when compared to usingconventional active monopole-like sources; as well as demonstrating how the variability of thebathymetry and environmental parameters affect the achievable coverage area of this passiveocean sensing technique in both shallow and deep water environments. The goal of this projectwill be to experimentally demonstrate that a library of estimated CIR from RBD of shippingsources can be used to passively update through-the-sensor our knowledge of the environmentaland geo-acoustic parameters."
