Popis: In this work, a computationally efficient evolutionary algorithm is proposed for estimating the direction of arrival (DOA) of coherently distributed (CD) sources corrupted by additive impulsive noise. The typical method, such as distributed signal parameter estimation (DSPE) method, requires a 2-D spectral peak search and cannot allow for coherent signals. The proposed method in this article uses an infinite norm (IN) normalization combined with the maximum likelihood (ML) criteria. The resulting cost function is solved using the introduced multimodal quantum-inspired benchmarking algorithm (MQBA), which obviously reduces the computational complexity without grid errors. The Cramer-Rao bound (CRB) for the considered DOA estimation problem is also derived. Finally, numerical simulations are conducted to show that our algorithm can perform superior robustness and allow for coherent signals without any additional process compared with alternative approaches for the considered scenarios. In addition, the proposedscheme can be popularized to address other DOA estimation problems and promote the development of DOA estimation.
