Paper Abstract

ERIM has developed a highly accurate method of simulating ocean backgrounds and targets in the infrared called Ship and Ocean Surface Image Simulation (SOSIS). This package provides realistic IR images of the ocean surface and horizon as a function of sea state, atmospheric conditions, sensor properties, and viewing geometry. SOSIS uses as inputs a thermal target model, an ocean surface model, and an environmental model. It samples these three models using a system of ray tracing and rough surface scattering to account for the interactions of the ocean surface, target, and the environment. At each ray-surface intersection, SOSIS takes into account small surface roughness, bi-directional reflection functions (BRDF's), solar glint, and polarization. The imagery from the SOSIS package is used for target signature prediction, weapons design, automatic target recognition (ATR) development, IR search and track (IRST) testing, ocean-horizon signatures, and many other functions.
