Spatial Limits on the Performance of Direction of Arrival Estimation
In this paper, we demonstrate that the performance of a direction of arrival (DOA) estimator is fundamentally limited by the size of the region over which we measure a wavefield. That is, even assuming continuous field measurements across the region, we still cannot achieve perfect performance. We use an approach based on modal decomposition of a spatially truncated field, and completely independent of sensor geometry, to derive the Cramér-Rao Bound (CRB) for spatially-limited DOA estimators....[Show more]
