Non-Coherent DOA Estimation of Off-Grid Signals With Uniform Circular Arrays
ICASSP 2021accepted
Recently, some non-coherent DOA estimation methods are presented under a sparse phase retrieval framework, where DOAs of incident signals are assumed to be on the predefined grid points. However, this may not be correct in practice; in order to address this issue, an off-grid model involved with a b…
