3D Imaging using Underwater LIDAR systems for rapid wide-area anti-mine and anti-submarine operations

LMDS

Detailed three-dimensional (3-D) imaging of the surface of the seafloor is essential for underwater exploration. Currently, the most widely used technology for exploration is sound navigation and ranging (SONAR), because acoustic waves can propagate through a long distance in water. However, SONAR suffers from unwanted multipass echoes that are due to …
