Abstract
This paper presents Derivative DFT Beamspace ESPRIT, a new closed-form algorithm for direction-of-arrival (DOA) estimation with uniform linear arrays or uniform rectangular arrays. The algorithm uses a novel virtual derivative DFT beamforming procedure to improve upon the performance of the recently developed DFT Beamspace ESPRIT algorithm. This beamforming procedure yields an additional invariance relationship which the algorithm exploits to obtain higher estimation accuracy (the algorithm is shown to outperform both DFT Beamspace ESPRIT and Unitary ESPRIT). Further, Derivative DFT Beamspace ESPRIT possesses all the attractive features (such as low computational complexity, and the ability to provide automatically paired source azimuth and elevation angle estimates) of the two aforementioned algorithms.
