Performance analysis of closed-form, ESPRIT based 2-D angle estimator for rectangular arrays
Electrical and Computer Engineering
IEEE Signal Processing Letters
The 2-D DFT beamspace ESPRIT is a recently developed algorithm for use in conjunction with uniform rectangular arrays (URA's) that provides automatically paired azimuth and elevation angle estimates of incident signals via a closed-form procedure. This letter investigates the statistical performance of 2D DFT beamspace ESPRIT. Expressions for the 2D DFT beamspace ESPRIT estimator variances are obtained. Samples variances of the azimuth and elevation angle estimates obtained through Monte Carlo simulations are shown to be in close agreement with theoretically predicted variances.
