The scintillation phase error (SPE) is a dominant factor that leads to azimuth decorrelation. The aperture-dependent and spatial-varying characteristics of the SPE promote the complexity of the SPE estimation and compensation. In this paper, a methodology is described that compensates the SPE by estimating the Faraday rotation (FR) angle from fully polarimetric SAR data. The multi-aperture scheme is adopted, including the sub-aperture FR estimation, multi-aperture splicing, and overall compensation, to take the complicated characteristics of the aperture-dependent and spatial-varying SPE into account. The methodology is finally validated on simulated data derived from the airborne P-band SAR real data, and compared with an existing method. The new method does not need prior knowledge of the ionospheric height. Furthermore, its performance is investigated in relation to several key factors in different simulation conditions.<\/jats:p>","DOI":"10.3390\/rs14225659","type":"journal-article","created":{"date-parts":[[2022,11,10]],"date-time":"2022-11-10T02:07:48Z","timestamp":1668046068000},"page":"5659","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Ionospheric Phase Scintillation Correction Based on Multi-Aperture Faraday Rotation Estimation in Spaceborne P-Band Full-Polarimetric SAR Data"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4500-3753","authenticated-orcid":false,"given":"Feixiang","family":"Tang","sequence":"first","affiliation":[{"name":"College of Electronic Science and Technology, National University of Defense Technology (NUDT), Changsha 410073, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6794-5015","authenticated-orcid":false,"given":"Yifei","family":"Ji","sequence":"additional","affiliation":[{"name":"College of Electronic Science and Technology, National University of Defense Technology (NUDT), Changsha 410073, China"}]},{"given":"Yongsheng","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Electronic Science and Technology, National University of Defense Technology (NUDT), Changsha 410073, China"}]},{"given":"Zhen","family":"Dong","sequence":"additional","affiliation":[{"name":"College of Electronic Science and Technology, National University of Defense Technology (NUDT), Changsha 410073, China"}]},{"given":"Baidong","family":"Yao","sequence":"additional","affiliation":[{"name":"East China Research Institute of Electronic Engineering, China Electronics Technology Corporation, Hefei 230031, China"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"412","DOI":"10.1109\/36.134090","article-title":"Dependence of radar backscatter on coniferous forest biomass","volume":"30","author":"Dobson","year":"1992","journal-title":"IEEE Trans.
