Focusing on the problem, an algorithm based on the fusion of multiscale superpixel segmentations is proposed in this paper. Firstly, the SAR images are partitioned by using different scales of superpixel segmentation. For the superpixels in each scale, the land-sea segmentation is achieved by judging their statistical properties. Then, the land-sea segmentation results obtained in each scale are combined with the result of the constant false alarm rate (CFAR) detector to eliminate the false alarms located on the land areas of the SAR image. In the end, to enhance the robustness of the proposed algorithm, the detection results obtained in different scales are fused together to realize the final target detection. Experimental results on real SAR images have verified the effectiveness of the proposed algorithm.<\/jats:p>","DOI":"10.3390\/s21051643","type":"journal-article","created":{"date-parts":[[2021,2,26]],"date-time":"2021-02-26T09:47:20Z","timestamp":1614332840000},"page":"1643","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Realizing Target Detection in SAR Images Based on Multiscale Superpixel Fusion"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6724-8647","authenticated-orcid":false,"given":"Ming","family":"Liu","sequence":"first","affiliation":[{"name":"Key Laboratory of Modern Teaching Technology, Ministry of Education, Xi\u2019an 710062, China"},{"name":"School of Computer Science, Shaanxi Normal University, Xi\u2019an 710119, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shichao","family":"Chen","sequence":"additional","affiliation":[{"name":"No. 203 Research Institute of China Ordnance Industries, Xi\u2019an 710065, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fugang","family":"Lu","sequence":"additional","affiliation":[{"name":"No. 203 Research Institute of China Ordnance Industries, Xi\u2019an 710065, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mengdao","family":"Xing","sequence":"additional","affiliation":[{"name":"National Laboratory of Radar Signal Processing, Xidian University, Xi\u2019an 710071, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jingbiao","family":"Wei","sequence":"additional","affiliation":[{"name":"Army Aviation Research Institute, Beijing 101121, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,2,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"4486","DOI":"10.1109\/JSTARS.2019.2951199","article-title":"Ground maneuvering targets imaging for synthetic aperture radar based on second-order keystone transform and high-order motion parameter estimation","volume":"12","author":"Zeng","year":"2019","journal-title":"IEEE J.
