Interactive 3-D Visualization of Underwater Sound Propagation via Fast Computation
Abstract
The operational success of the fast attack submarine fleet to track and avoid detection by other submerged and surface self-powered,vessels is critically dependent on the real-time analysis of their passive sonar assets that provide information about the ambient s,onar environment. Such data suffers from a number of initial ambiguities such as range, depth, and heading of the object of interest, based on the limitations of the collecting device. So, for example, using a linear towed array, beam-forming techniques can only in,dicate the horizontal angles of arrival of the ambient acoustic environment because it is essentially a one-dimensional receiver. Co,nfronted with the time evolving nature of this information, the submariner needs to make decisions about how to resolve these ambigu,ities to localize and track, while at the same time avoid detection.In the context of these considerations, and with regard to incre,asing the submarine operators knowledge of the environment, its uncertainties, and the potential for detection of both the adversar,y and formulating strategies for both searching and tracking it, we will create a visually rich display environment that conveys thi,s information in a format that is intuitive and interactive. This will include both the use of a 3-D visualization program like Unit,y (2021) or Unreal (2021). Our software will allow interactive display and perform fast, GPU based, computation of the acoustic fiel,ds, given source locations and the sound speed parameters of the environment. We also plan to work with other researchers that are p,roducing 3-D underwater sound field data as well as those that maintain centers for visualization of geomorphology using Unity.This,abstract is publicly releasable.
