The objective of this study is to evaluate the performance of different polarimetric calibration methods. Two widely used methods, the Van Zyl and Quegan methods, and one recently proposed method, such as the Villa method, have been selected among various calibration methods in literature. The selected methods have basic differences in their assumptions that are applied to the polarimetric system model. In order to evaluate the calibration performances under different system parameters and ground characteristics, comparative analysis of the calibration results were conducted on synthetic polarimetric SAR data and ALOS PALSAR quad-pol mode data. Based on the experimental results, the advantages and limitations of different methods were clarified, and a simple hybrid calibration method is presented to further improve the polarimetric calibration performance.<\/jats:p>","DOI":"10.3390\/rs10122060","type":"journal-article","created":{"date-parts":[[2018,12,18]],"date-time":"2018-12-18T11:09:21Z","timestamp":1545131361000},"page":"2060","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Comparative Analysis of Polarimetric SAR Calibration Methods"],"prefix":"10.3390","volume":"10","author":[{"given":"Yoon Taek","family":"Jung","sequence":"first","affiliation":[{"name":"Department of Geoinformation Engineering, Sejong University, 209, Neungdong-ro, Gwangjin-gu, Seoul 05006, Korea"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0887-1348","authenticated-orcid":false,"given":"Sang-Eun","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Geoinformation Engineering, Sejong University, 209, Neungdong-ro, Gwangjin-gu, Seoul 05006, Korea"}]}],"member":"1968","published-online":{"date-parts":[[2018,12,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"337","DOI":"10.1109\/36.54360","article-title":"Calibration of polarimetric radar images using only image parameters and trihedral corner reflector responses","volume":"28","year":"1990","journal-title":"IEEE Trans.
