2-D DOA Estimation Method Based on Joint SVD

A new 3D array shape and the corresponding estimation 2-D DOAs algorithm based on joint SVD is proposed in this paper.This new array shape extends DOA estimation scope and improves the estimator performance relative to the planar array.It adopts the cross-correlation among the sub-arrays other than the auto-correlation of the sub-arrays,thus to effectively depress the influence of noise.And the pairing method is completed by joint SVD.Finally,it is proved that the proposed method is superior in estimation scope and the estimation performance.
