Performance analysis of root-music-based direction-of-arrival estimation for arbitrary non-uniform array
Michael Rübsamen, Alex B. Gershman · 2008
We present the asymptotic performance analysis of the interpolated root-MUSIC and manifold separation (MS) techniques for direction-of-arrival (DOA) estimation in arbitrary non-uniform sensor arrays. Our analysis takes into account both the effects of a limited number of snapshots and manifold approximation errors.
