Description
Summary:	This paper introduces an airborne system that was conceptualized and designed to detect submerged objects, day and night, optically from manned and unmanned aircraft. This system was designed with strict size, weight and power constraints and to work with ship-based Tier2/Tier3 UAVs. Daytime detection is accomplished through multi-spectral imaging mixing methods, and nighttime imaging capability is reliant on sensing the light signatures from disturbed marine bioluminescent organisms. This paper describes the methodology used to determine the detector, lens and filters, the mechanical design and associated calibration techniques, and the image processing method used. It also presents the data obtained from preliminary field tests and discusses planned future work based on these results. This system could potentially be useful for protecting both ships and marine mammals from inadvertent collisions, particularly at night, as well bring additional capability to the USCG in their maritime, counter-drug missions.
