Abstract:

The long-term goals of this research are to develop the control methodology for active cloaking of underwater assets and the initial hardware concepts to test the proposed cloaking approach. This work is a natural extension of ONR Project N00014-02-1-0211 Optical Variability and Bottom Classification in Turbid Waters HyMOM Predictions of the Light Field in Ports and Beneath Ship Hulls where the perceptibility of underwater assets was modeled. The initial objective of this work is to extend the existing 3-D Hybrid Marine Optical Model HyMOM to determine the three-dimensional light structure of representative marine environments in order to calculate the character of the radiance field needed to remove asset contrast with the background. A secondary objective is to develop a practical method to provide the additional radiance necessary to accomplish this task and to make the asset self-aware of its background contrast. Only in this manner will the asset be able to change radiance fields with environmental conditions.
