In this paper, the relationship between the USV and conventional steering vector (CSV) which corresponds to the array factor is described, and moreover the relationship of USV and the practical steering vector or manifold including both the mutual coupling between array elements and the gain/phase errors of RF channels is investigated. The numerical simulation results show that the numerical USV can obtain very good accuracy for MUSIC-based DOA estimation if the effect only comes from array configuration such as the mutual coupling between array elements and reflector, element position and so on. The experimental result shows that the steering vector including all effects can estimate DOA correctly and also demonstrates that the practical steering vector can be obtained by multiplying the numerical USV with a DOA-independent compensation matrix. |
