摘要：

Most　existing　Direction-of-arrival　(DOA)　and　polarization　estimation　methods,　which　are　based　on　polarization　sensitive　array,　generally　assume　that　array　element　orient　the　referenced　Cartesian　coordinates　strictly,　that　is　no　misorientation.　However,　in　practical　applications　array　elements　have　misorientations,　and　it　is　necessary　to　calibrate　the　misorientations.　To　solve　this　problem,　a　Taylor　approximate　expansion　iterative　method　is　proposed.　It　uses　the　first-order　Taylor　approximate　expansion　to　calibrate　the　array　elements　repeatedly　to　get　the　array＇s　misorientation　matrix.　The　simulation　results　show　that　the　estimation　of　DOA　and　polarization　are　quite　close　to　the　true　values　by　using　the　proposed　method.　©　2016,　Editorial　Board　of　Jilin　University.　All　right　reserved.
