Abstract：

A　study　on　the　method　of　direction　of　arrival　(DOA)　estimation　for　many　groups　of　coherent　and　uncorrelated　sources　under　nonstationary　noise　fields　is　described　in　this　paper.　The　proposed　algorithm　can　separate　the　uncorrelated　and　coherent　sources　by　making　use　of　oblique　projection,　and　it　uses　fewer　sensors　when　estimating　the　same　sources　compared　with　the　conventional　methods.　Further　more,　the　effect　of　the　nonstationary　noise　is　eliminated　because　it　is　translated　into　white　noise　using　improved　Toeplitz　matrix.　At　the　same　time,　the　performance　of　many　algorithms　is　compared　by　simulation,　the　effectiveness　and　accuracy　of　the　proposed　algorithm　is　verified.　©　Springer-Verlag　Berlin　Heidelberg　2012.
