For this problem, it is not only necessary to find the optimal polarization states such that the received power ratio of a desired target and clutter is maximal, but also necessary to find three optimal coefficients such that the ratio of two factors associated with the desired target and clutter is maximal, where both the factors consist of three parameters, i.e., the Cloude entropy and two special similarity parameters. The optimal coefficients of the GOPCE are obtained by solving an eigenvalue problem. Using an example, we demonstrate that the GOPCE can be employed for detecting roads in a forest area by using polarimetric synthetic aperture radar data.IEEE2004-07engjournal articlehttp://hdl.handle.net/10191/4988https://niigata-u.repo.nii.ac.jp/records/1709info:doi/10.1109/LGRS.2004.830127AA118958711545598XIEEE geoscience and remote sensing lettersIEEE geoscience and remote sensing letters13171174https://niigata-u.repo.nii.ac.jp/record/1709/files/(Yamaguchi gereralized)01315625.pdfapplication/pdf506.9 kB2019-07-29
