Paper Abstract

Detecting and identifying targets immersed in draught zone are necessary for a safe navigation. But with today technologies it is very difficult to do it from a ship. Nowadays, this detection still stays a challenge, because sonars are inefficient in the zone just under the waterline. In our laboratory we succeeded in using lidar as a complementary tool of the sonar. With optical detection, active imagery, various immersed targets were detected, identified and classified according to a Mueller matrix and whatever the perturbations on the sea surface and the wind conditions. The possibility of using a particular polarimetric codage with optical signal is discussed in this paper. The aim was to demonstrate that our lidar tool can be improved by choosing the best polarimetric couple in emission and detection.
