In this paper, a modified hybrid Freeman\/eigenvalue decomposition method for the coherency matrix derived from the fully PolSAR sensors is proposed. The proposed modified hybrid Freeman\/eigenvalue decomposition uses a real unitary transformation on the coherency matrix to release correlations between the copolarized term and cross polarized term, and the scattering models are derived from eigenvectors of the coherency matrix with reflection symmetry condition. The anisotropy and entropy are used to determine whether the volume scattering component is derived from the man-made structures or not. Moreover, the scattering powers from the proposed hybrid Freeman\/eigenvalue decomposition are all nonnegative values. Fully PolSAR data on San Francisco acquired by AIRSAR sensor are used in the experiments to prove the efficacy of the proposed decomposition.<\/jats:p>","DOI":"10.1155\/2015\/168720","type":"journal-article","created":{"date-parts":[[2015,10,20]],"date-time":"2015-10-20T17:04:02Z","timestamp":1445360642000},"page":"1-7","source":"Crossref","is-referenced-by-count":3,"title":["Modified Hybrid Freeman\/Eigenvalue Decomposition for Polarimetric SAR Data"],"prefix":"10.1155","volume":"2015","author":[{"given":"Shuang","family":"Zhang","sequence":"first","affiliation":[{"name":"Key Laboratory of Intelligent Perception and Image Understanding of Ministry of Education, International Research Center for Intelligent Perception and Computation, Xidian University, Xi\u2019an, Shaanxi 710071, China"}]},{"given":"Shuang","family":"Wang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Intelligent Perception and Image Understanding of Ministry of Education, International Research Center for Intelligent Perception and Computation, Xidian University, Xi\u2019an, Shaanxi 710071, China"}]},{"given":"Bo","family":"Chen","sequence":"additional","affiliation":[{"name":"Key Laboratory of Intelligent Perception and Image Understanding of Ministry of Education, International Research Center for Intelligent Perception and Computation, Xidian University, Xi\u2019an, Shaanxi 710071, China"}]}],"member":"311","reference":[{"key":"2","doi-asserted-by":"publisher","DOI":"10.1109\/36.729356"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1109\/36.485127"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1109\/36.551935"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1109\/36.673687"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1109\/TGRS.2005.852084"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1109\/TGRS.2010.2099124"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1109\/tgrs.2011.2138146"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1109\/TGRS.2010.2041242"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1109\/TGRS.2012.2212446"},{"year":"2009","key":"14"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1109\/LGRS.2012.2193373"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1109\/TGRS.2005.855064"},{"year":"2009","key":"17"}],"container-title":["Journal of Sensors"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2015\/168720.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2015\/168720.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2015\/168720.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2016,8,18]],"date-time":"2016-08-18T09:09:52Z","timestamp":1471511392000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/js\/2015\/168720\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015]]},"references-count":13,"alternative-id":["168720","168720"],"URL":"https:\/\/doi.org\/10.1155\/2015\/168720","relation":{},"ISSN":["1687-725X","1687-7268"],"issn-type":[{"type":"print","value":"1687-725X"},{"type":"electronic","value":"1687-7268"}],"subject":[],"published":{"date-parts":[[2015]]}}}
