Executive Summary

In this paper, the authors propose a new technique that makes use of Angle-of-Arrival (AoA) information in conjunction with local inter-ferometry to improve target location estimation. They call this process Angle-of-arrival-assisted Radio Inter-ferometry (ARI). It has a number of desirable attributes including the ability to reduce the synchronization, network, and hardware requirements when operating as the sole RADAR modality and its ability to augment existing pulsed and CW RADAR algorithms. The proposed approach is described and analyzed.
