Tolerance on element failure for DoA estimation: A soft-computing approach
The Direction of Arrival (DoA) estimation of signals impinging on a failed antenna array is approached as an optimization problem and solved by using particle swarm optimization (PSO) technique with single snapshot. The performance and usefulness of this algorithm is analyzed under different failure scenarios and also in different noisy environment. In this paper we have made a study on the tolerance level of this element failure, for which the estimated value of DoA remain in acceptable limit. Results show that a PSO algorithm is capable of solving the problem of DoA estimation under element failure scenario.
