The IR image wavelength-band conversion which transforms one arbitrary IR wavelength-band image to another IR wavelength-band image is needed for IR signature modeling and image synthesis in the IR systems. However, the IR wavelength-band conversion is very challenging because absorptivity and transmittance of objects and background (atmosphere) are different according to the IR wavelength band and because radiation and reflectance characteristics of the SWIR are very different from the LWIR and MWIR. Therefore, the IR wavelength-band conversion in this paper applies to only IR targets and monotonous backgrounds at a long distance for military purposes. This paper proposes an IR wavelength-band conversion method which transforms one arbitrary IR wavelength-band image to another IR wavelength-band image by using the surface temperature estimation of an object and the error attenuation method for the estimated temperature. The surface temperature of the object is estimated by an approximated Planck\u2019s radiation equation and the error of estimated temperature is corrected by using the slope information of exact radiance along with the approximated one. The corrected surface temperature is used for generating another IR wavelength-band image. The verification of the proposed method is demonstrated through the simulations using actual IR images obtained by thermal equipment.<\/jats:p>","DOI":"10.3390\/s19112455","type":"journal-article","created":{"date-parts":[[2019,5,29]],"date-time":"2019-05-29T11:31:28Z","timestamp":1559129488000},"page":"2455","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["IR-Band Conversion of Target and Background Using Surface Temperature Estimation and Error Compensation for Military IR Sensor Simulation"],"prefix":"10.3390","volume":"19","author":[{"given":"Taewuk","family":"Bae","sequence":"first","affiliation":[{"name":"Daegu-Gyeongbuk Research Center, Electronics and Telecommunications Research Institute, Daegu 42994, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Youngchoon","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Information and Communication Security, U1 University, Asan 31415, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sangho","family":"Ahn","sequence":"additional","affiliation":[{"name":"Department of Electronic Telecommunications, Mechanical &amp; Automotive Engineering, Inje University, Kimhae 50834, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,5,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"42","DOI":"10.1016\/j.infrared.2013.12.007","article-title":"Spatial and temporal bilateral filter for infrared small target enhancement","volume":"63","author":"Bae","year":"2014","journal-title":"Infrared Phys.
