The effect of mutual coupling in antenna elements heavily deteriorates the performance of existing array-based bearing-finding methods. Such a bias of MUSIC in uniform and general linear arrays is analytically studied and an explicit expression of a relationship between this bias and the effect of mutual coupling together with the direction of the incident source is given. The biases of different arrays are also compared to provide a reference when choosing the right array under the considerable effect of mutual coupling.
