The ensemble averaged coherency matrix in an imaging window derived using a scattering matrix has all non-zero elements in its three-by-three matrix. It is a full 3 \u00d7 3 matrix that bears nine real-valued and independent polarimetric parameters inside. In the proposed decomposition method, G5U, we preprocess observed coherency matrix [T] by using two consecutive unitary transformations to become an ideal form for five-component decomposition. The transformation reduces nine parameters to seven, which is the best fit for five-component scattering model expansion. We can retrieve five powers corresponding to surface scattering, double bounce scattering, volume scattering, oriented dipole scattering, and compound dipole scattering, directly. These powers can be calculated easily and used to display superb polarimetric RBG images as never before, and are further applicable for polarimetric calibration, classification, validation, etc.<\/jats:p>","DOI":"10.3390\/rs15051332","type":"journal-article","created":{"date-parts":[[2023,2,28]],"date-time":"2023-02-28T02:01:51Z","timestamp":1677549711000},"page":"1332","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["General Five-Component Scattering Power Decomposition with Unitary Transformation (G5U) of Coherency Matrix"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-4900-1342","authenticated-orcid":false,"given":"Rashmi","family":"Malik","sequence":"first","affiliation":[{"name":"Department of Civil Engineering, Indian Institute of Technology Kanpur, Kanpur 208016, India"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7774-5997","authenticated-orcid":false,"given":"Gulab","family":"Singh","sequence":"additional","affiliation":[{"name":"Centre of Studies in Resources Engineering, Indian Institute of Technology Bombay, Mumbai 400076, India"}]},{"given":"Onkar","family":"Dikshit","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, Indian Institute of Technology Kanpur, Kanpur 208016, India"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4144-8760","authenticated-orcid":false,"given":"Yoshio","family":"Yamaguchi","sequence":"additional","affiliation":[{"name":"Faculty of Engineering, Niigata University, Niigata 950-2181, Japan"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,27]]},"reference":[{"key":"ref_1","unstructured":"Lee, J.S., and Pottier, E.
