Abstract
The mutual coupling effect in practical arrays is hard to eliminate completely, and such effect brings a deterministic bias into the direction-of-arrival (DOA) estimates for non-circular signals. The bias is analysed in this study and closed-form expressions for the biases in uniform linear arrays (ULA) and general linear arrays (GLA) are given. Numerical examples are carried out to verify the correctness of the theoretical biases in various signal environments.
