Abstract
A method to estimate direction of arrival (DOA) of multi-band signals is proposed in this paper. The authors apply the compressed sensing theory which can reconstruct sparse data in a few measurements, to multi-band signals. Compared to various DOA estimation methods, this approach has produced a considerable improvement of DOA estimation accuracy. Moreover, this proposal can estimate more waves than the degrees of freedom of the array.
