Effect of mutual coupling on direction-of-arrival estimation using sparse dipole arrays

摘要

The effect of mutual coupling on the direction-of-arrival (DOA) estimation using sparse arrays of dipole antennas is investigated. The open circuit method is used to model the mutual coupling. DOA estimation performance in the presence of mutual coupling is compared and contrasted for different array configurations, namely, uniform linear arrays, minimum redundancy arrays, nested arrays, and co-prime arrays.
