Due to the azimuth sensitivity of SAR images, the inner correlation between multiview images participating in recognition is not stable enough. To this end, the proposed method first clusters multiview SAR images based on image correlation and nonlinear correlation information entropy (NCIE) in order to obtain multiple view sets with strong internal correlations. For each view set, the multitask sparse representation is used to reconstruct the SAR images in it to obtain high\u2010precision reconstructions. Finally, the linear weighting method is used to fuse the reconstruction errors from different view sets and the target category is determined according to the fusion error. In the experiment, the tests are conducted based on the MSTAR dataset, and the results validate the effectiveness of the proposed method.<\/jats:p>","DOI":"10.1155\/2021\/9703709","type":"journal-article","created":{"date-parts":[[2021,11,25]],"date-time":"2021-11-25T00:20:07Z","timestamp":1637799607000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["A Multiview SAR Target Recognition Method Using Inner Correlation Analysis"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2880-2625","authenticated-orcid":false,"given":"Lei","family":"Lei","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3927-7616","authenticated-orcid":false,"given":"Dongen","family":"Guo","sequence":"additional","affiliation":[]},{"given":"Zhihui","family":"Feng","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2021,11,24]]},"reference":[{"key":"e_1_2_9_1_2","doi-asserted-by":"publisher","DOI":"10.1109\/access.2016.2611492"},{"key":"e_1_2_9_2_2","doi-asserted-by":"publisher","DOI":"10.1049\/iet-cvi.2013.0027"},{"key":"e_1_2_9_3_2","doi-asserted-by":"publisher","DOI":"10.1117\/1.jrs.10.046006"},{"key":"e_1_2_9_4_2","doi-asserted-by":"publisher","DOI":"10.1155\/2018\/9680465"},{"key":"e_1_2_9_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijleo.2019.04.014"},{"key":"e_1_2_9_6_2","doi-asserted-by":"publisher","DOI":"10.1080\/09205071.2018.1495580"},{"key":"e_1_2_9_7_2","doi-asserted-by":"publisher","DOI":"10.1109\/taes.2012.6178042"},{"key":"e_1_2_9_8_2","doi-asserted-by":"crossref","unstructured":"MishraA.
