ACTIVE IMAGERY UNDER GRAZING INCIDENCE USING POLARIZATION TO DETECT AND IDENTIFY SUBSURFACE TARGETS IMMERSED IN THE DRAUGHT ZONE

摘要

The possibility of detecting and identifying targets immersed in the draught zone of a ship with a lidar is discussed in this paper. It is carried out by a polarimetric codification of optical signals. The sea surface roughness, in conjunction with wind direction, greatly disturbs light dispersion. Nevertheless, by using the Stokes-Mueller polarimetric formalism, a classification of immersed targets with various surfaces and covering properties can be laid down. [References: 10]
