摘要：

A novel joint diagonalization spatio-temporal fractional lower order moments direction of arrival (DOA) matrix method is proposed to estimate the 2-D DOA of uncorrelated narrowband signals with arbitrary array configuration in the presence of impulsive noise. The new method first constructs pseudo data matrix by collecting the pseudo snapshots of fractional lower-order spatio-temporal (ST) matrix, then performs a joint diagonalization fractional lower-order spatio-temporal moment process. It can handle sources with common 1-D angles with neither peak searching nor parameter pairing. Simulation results show that the proposed method is effective.
