A new approach is proposed for DOA estimation in nonuniform linear arrays (NLA) based on array interpolation. A Wiener formulation is presented to improve the condition number of the mapping matrix as ...

Coherent wideband DOA estimation for non-uniform linear arrays (NLA) is considered. Array interpolation is used for two mappings. In the first mapping, NLA is mapped to a uniform linear array with the ...

We propose a framework that projects to approximate 2D functions through a series of 1D interpolations and also uses greedy sampling. By generating uniformly distributed projections and projecting ...
