DOA and Polarization Angle Estimation Algorithm Based on Sparse Signal Reconstruction
Existing direction-of-arrival and polarization estimation methods mostly rely on subspace technique.This paper proposes a novel DOA and polarization angle estimation algorithm from sparse signal reconstruction perspective.The algorithm first constructs a cumulant matrix model which is only related to DOA parameter
and then obtains DOA estimation using the weighted l

-norm minimization.Further
this paper constructs another three cumulant vector models by sum-average arithmetic
and enforces sparsity by Zhang penalty
which leads to almost unbiased polarization angle estimation.Meanwhile
this paper also demonstrates how to identify two sources with same DOA using their polarization characteristics.Compu
ter simulation results validate the effectiveness of the proposed algorithm.
