In　this　paper,　a　new　method　about　two　dimension　direction　of　arrival　(2D　DOA)　estimation　is　proposed　for　the　mixture　of　circular　signals　and　non-circular　signals　based　on　uniform　rectangular　array(URA).This　proposed　method　combines　unitary　estimation　of　signal　parameters　via　rotational　invariant　technique(Unitary　ESPRIT)　algorithm　with　a　technology　called　joint　diagonalization(JD),　which　aims　at　solving　the　problem　of　angle　mergence　and　angle　matching.　We　establish　a　new　observed　data　matrix　fully　exploiting　the　second　order-noncircular　(SO-NC)　property　of　mixed　signals　and　convert　complex　operations　into　real-valued　operations　by　Unitary　ESPRIT　algorithm.　And　we　are　able　to　successfully　distinguish　mixed　angles　through　JD　when　mixed　signals　has　the　same　angles　in　one　dimension,　which　can　also　acquire　automatically　angles.　The　simulation　results　show　the　effectiveness　of　our　proposed　method.
