SPIE Newsroom — “Detecting naval vessels based on their IR characteristics is a key task for many defense organizations.
“The emissions (i.e., the shape and thermal energy) of such vessels produce an overall IR signature that can be analyzed to detect and, subsequently, to track them.
“For this reason, numerous models have been developed over the years to predict the IR signature of ships.1
“The hot exhaust gases that are produced by a ship’s engine represent one of the main contributions to its signature. Many modern military vessels are therefore equipped with IR-signature suppression systems (i.e., where steam is injected into the exhaust gases to reduce their self-emission).2 (more…)
