- W2185935187 abstract "Partly-filled nonuniform linear arrays (PFNLA)arepresented and DOA estimation problem formultipath signals isinvestigated. A newapproach isproposed forDOA estimation innonuniform linear arrays (NLA)based onarray interpolation. A Wiener formulation is usedtoimprove thecondition number ofthemapping matrix aswell astheperformance fornoisy observations. Aninitial DOA estimate isobtained byusing theuniform part ofthePFNLA.Thisinitial estimate isusedinarray interpolation andanewcovariance matrix is foundwhichimproves theDOA estimation significantly. Noniterative anditerative algorithms aredeveloped fortheDOA estimation in multipath. Proposed approach overcomes someofthelimitations of theconventional array interpolation. Itisshownthat theDOA performance isclose totheCRBandthemethod isrobust foravariety ofsource andDOA scenarios. IndexTerms-Direction ofarrival estimation, nonuniformly spaced arrays, music, array signal processing, multipath" @default.
