Passive Defense Measures in IR Signatures Suppression of Military Ships

One of the important aspects of stealth technology in advanced warships design has been discussed In this paper. In warships, infrared suppression is vital to mitigate threats against infrared guided missiles. Infrared radiation is introduced and then definition of the physical concepts of spectral emission and radiance and introduction of theoretical expression are represented. Ships infrared emission sources and methods of their suppression were studied and infrared suppression systems common in advanced military ships are listed.
