Based on the physical interpretation of polarimetric decomposition theory and the Lasso rule for sparse features, we propose a four-component decomposition model, which is composed of surface scattering (Odd), double-bounce scattering (Dbl), volume scattering (Vol), and \u00b145\u00b0 oriented dipole (Od). In principle, the Od component can describe the compounded scattering structure of a ship consisting of odd-bounce and even-bounce reflectors. Moreover, the pocket perceptron learning algorithm (PPLA) and support vector machine (SVM) are utilized to solve the linear inseparable problems in this study. Using large amounts of RADARSAT-2 (RS-2) fully polarized SAR data and AIRSAR data, our experimental results show that the Od component can make a great contribution to ship detection. Compared with other conventional decomposition methods used in the experiments, the proposed four-component decomposition method has better performance and is more effective and feasible to detect ships.<\/jats:p>","DOI":"10.3390\/rs16010178","type":"journal-article","created":{"date-parts":[[2023,12,31]],"date-time":"2023-12-31T10:01:06Z","timestamp":1704016866000},"page":"178","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["A Novel Polarization Scattering Decomposition Model and Its Application to Ship Detection"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6268-6173","authenticated-orcid":false,"given":"Lu","family":"Fang","sequence":"first","affiliation":[{"name":"School of Electronic Engineering, Naval University of Engineering, Wuhan 430033, China"}]},{"given":"Ziyuan","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Electronic Engineering, Naval University of Engineering, Wuhan 430033, China"}]},{"given":"Wenxing","family":"Mu","sequence":"additional","affiliation":[{"name":"School of Electronic Engineering, Naval University of Engineering, Wuhan 430033, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9596-4536","authenticated-orcid":false,"given":"Tao","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Electronic Engineering, Naval University of Engineering, Wuhan 430033, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,12,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"391","DOI":"10.1109\/LGRS.2010.2078796","article-title":"Ship Detection in Ice-Infested Waters Based on Dual-Polarization SAR Imagery","volume":"8","author":"Brekke","year":"2011","journal-title":"IEEE Geosci.
