Abstract

In this work an exclusive hyperspectral imaging system was implemented to detect immerged and sub-immerged targets in aqua environments using laser illumination. Under different water extinction levels the system was capable of detecting and differentiating between several dummy targets with different colors and shapes. A study of the effect of deep background on the target identification is also inclusive. The tests revealed a strong dependence of target detectivity on the laser wavelength, the water turbidity, and target surface shape and color. This work helps in the future design of airborne underwater target detection system capable of tracking stealth submarine at different depths and aqua environments.
