Abstract：

A　study　on　the　method　of　direction　of　arrival(DOA)　estimation　for　many　groups　of　coherent　and　uncorrelated　sources　under　mutual　coupling　based　on　MMUSIC　is　described　in　this　paper.　The　method　decoherences　the　coherent　sources　by　the　use　of　MMUSIC　firstly.　Then,　the　method　estimates　the　mutual　coupling　parameter　of　the　linear　array　and　the　DOA　of　every　signal　using　minimal　optimization　function.　The　method　improves　the　utilization　rate　of　the　array.　At　the　same　time,　it　has　a　high　accuracy.　The　performance　of　many　relevant　algorithms　is　compared　by　simulations,　the　effectiveness　and　accuracy　of　the　proposed　algorithm　is　verified.　©　2012　IEEE.
