摘要: A new method is proposed to estimate the direction-of-arrival (DOA) based on uniform linear array sampling and named as sparsity temporal correlation exploiting (SaTC-E). By structure information of source signals, including spatial sources, SaTC-E accomplishes DOA estimation with superior performance via block sparse bayesian learning methodology grid refined strategy. applicable into time-varying manifold scenario, such wideband array, provided that matrix determinable. It has improved some other merits, resolution, requirement for a few snapshots, no knowledge number, applicability spatially temporally corrected sources. Real data tests numerical simulations are carried out demonstrate advantages SaTC-E.
