Infrared tracking, also known as infrared homing, refers to a [[Passive homing|passive missile guidance system]], which uses the [[light emission|emission]] from a target of electromagnetic radiation in the infrared part of the spectrum to track it. Missiles that use infrared seeking are often referred to as "heat-seekers" since infrared (IR) is just below the visible spectrum of light in frequency and is radiated strongly by hot bodies. Many objects such as people, vehicle engines, and aircraft generate and retain heat, and as such, are especially visible in the infrared wavelengths of light compared to objects in the background.<ref>{{Cite journal |last=Mahulikar, S.P. |last2=Sonawane, H.R. |last3=Rao, G.A. |year=2007 |title=Infrared signature studies of aerospace vehicles |url=http://dspace.library.iitb.ac.in/xmlui/bitstream/handle/10054/613/5740.pdf |url-status=live |journal=Progress in Aerospace Sciences |volume=43 |issue=7–8 |pages=218–245 |bibcode=2007PrAeS..43..218M |citeseerx=10.1.1.456.9135 |doi=10.1016/j.paerosci.2007.06.002 |archive-url=https://web.archive.org/web/20210304165104/http://dspace.library.iitb.ac.in/xmlui/bitstream/handle/10054/613/5740.pdf |archive-date=2021-03-04 |access-date=2013-04-12}}</ref>
