    Abstract

    Angle-of-Arrival (AoA) estimation supports beamforming that controls array beams in a desired direction while eliminating interference signals. In this paper, we propose a blind AoA estimation method with low complexity by applying a monopulse radar processing method to an antenna array. This paper aims to investigate the statistical characteristics of monopulse signal R for the performance analysis. Monopulse signal ratio R is modeled as the ratio of quadratic random variables in the form of \mathrm{x}^{\prime}\mathrm{Ax}/\mathrm{x}^{\prime}\mathrm{Bx}, where A and B are indefinite and positive semidefinite matrices, respectively. In this paper we obtain the probability density function (PDF) of R. Furthermore, we confirm that the monopulse based AoA estimator (MAoA) is comparable to the single-target estimation performance of subspace-based algorithms with high complexity such as multiple signal classification (MUSIC) and estimation of signal parameters via rotational invariance technique (ESPRIT) in terms of mean square error (MSE).
