A computationally efficient direction of arrival (DOA) estimation algorithm for closely spaced targets is proposed. The algorithm comprises two parts: an algorithm for discriminating closely spaced targets from a single target, and an algorithm for resolving the directions of arrival of the closely spaced targets. Simulations show that the proposed algorithm performs well with a low computational cost.
