This model introduces a simple yet accurate method for the selection of the optical bands for target detection based on multispectral features. The key to this model is the selection of the spectral bands in which a significant radiation difference exists between the target and its surrounding background. Using the signal-to-noise ratio (SNR), detection probability, and false alarm rate as model evaluation metrics, and based on the analysis of the radiation differences between the target and atmospheric background, it is found that there are two narrow bands possible for SA detection: one with a central wavelength of 8.83 \u00b5m and a bandwidth of 0.35 \u00b5m and the other with a central wavelength of 11.51 \u00b5m and a bandwidth of 0.34 \u00b5m. Further numerical simulations and theoretical analyses under varying space environments demonstrate that considerable detection potential can be achieved; thus, the presented optical detection model is useful for the night detection of SA targets.<\/jats:p>","DOI":"10.3390\/rs16111884","type":"journal-article","created":{"date-parts":[[2024,5,24]],"date-time":"2024-05-24T11:17:52Z","timestamp":1716549472000},"page":"1884","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["An Optical Detection Model for Stratospheric Airships"],"prefix":"10.3390","volume":"16","author":[{"given":"Huiqiang","family":"Xu","sequence":"first","affiliation":[{"name":"Key Laboratory of Atmospheric Optics, Anhui Institute of Optics and Fine Mechanics, HFIPS, Chinese Academy of Sciences, Hefei 230031, China"},{"name":"Science Island Branch of Graduate School, University of Science and Technology of China, Hefei 230026, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7949-6170","authenticated-orcid":false,"given":"Shengcheng","family":"Cui","sequence":"additional","affiliation":[{"name":"Key Laboratory of Atmospheric Optics, Anhui Institute of Optics and Fine Mechanics, HFIPS, Chinese Academy of Sciences, Hefei 230031, China"},{"name":"Nanhu Laser Laboratory, National University of Defense Technology, Changsha 410073, China"},{"name":"Advanced Laser Technology Laboratory of Anhui Province, Hefei 230037, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4408-6793","authenticated-orcid":false,"given":"Zhi","family":"Qiao","sequence":"additional","affiliation":[{"name":"Key Laboratory of Atmospheric Optics, Anhui Institute of Optics and Fine Mechanics, HFIPS, Chinese Academy of Sciences, Hefei 230031, China"},{"name":"Science Island Branch of Graduate School, University of Science and Technology of China, Hefei 230026, China"}]},{"given":"Xiaodan","family":"Liu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Atmospheric Optics, Anhui Institute of Optics and Fine Mechanics, HFIPS, Chinese Academy of Sciences, Hefei 230031, China"},{"name":"Science Island Branch of Graduate School, University of Science and Technology of China, Hefei 230026, China"}]},{"given":"Shizhi","family":"Yang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Atmospheric Optics, Anhui Institute of Optics and Fine Mechanics, HFIPS, Chinese Academy of Sciences, Hefei 230031, China"},{"name":"Nanhu Laser Laboratory, National University of Defense Technology, Changsha 410073, China"},{"name":"Advanced Laser Technology Laboratory of Anhui Province, Hefei 230037, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1209-2769","authenticated-orcid":false,"given":"Heli","family":"Wei","sequence":"additional","affiliation":[{"name":"Key Laboratory of Atmospheric Optics, Anhui Institute of Optics and Fine Mechanics, HFIPS, Chinese Academy of Sciences, Hefei 230031, China"},{"name":"Nanhu Laser Laboratory, National University of Defense Technology, Changsha 410073, China"},{"name":"Advanced Laser Technology Laboratory of Anhui Province, Hefei 230037, China"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,24]]},"container-title":["Remote Sensing"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.mdpi.com\/2072-4292\/16\/11\/1884\/pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,10]],"date-time":"2025-10-10T14:48:13Z","timestamp":1760107693000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.mdpi.com\/2072-4292\/16\/11\/1884"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,5,24]]},"references-count":0,"journal-issue":{"issue":"11","published-online":{"date-parts":[[2024,6]]}},"alternative-id":["rs16111884"],"URL":"https:\/\/doi.org\/10.3390\/rs16111884","relation":{},"ISSN":["2072-4292"],"issn-type":[{"type":"electronic","value":"2072-4292"}],"subject":[],"published":{"date-parts":[[2024,5,24]]}}}
