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 ...

One other thought circling in my mind is to have the DO's carry around a kind of master array that kind of goes from 0 to q=45 (about the widest range we will ever encounter) with a fine grid and we ...

In comparison to linear interpolation, use of splines in piecewise polynomial form reduced the CPU time to obtain results of equivalent accuracy by a factor of 250-330 for a stochastic 4-dimensional ...
