- Abstract
In this paper, we propose the noncircular estimation signal parameters via rotational invariance techniques (NC-ESPRIT) algorithm as a two-dimension direction of arrival (2D-DOA) estimation algorithm for uniform rectangular array. Compared to conventional circular ESPRIT algorithm, the proposed algorithm exploits the property of noncircular signals through data expansion, so that the array aperture is doubled. Therefore, the angle estimation performance is superior to that of the circular ESPRIT algorithm. Moreover the proposed algorithm has no spectral peak searching and the two-dimension angle estimates can be paired automatically. Simulation results illustrate the effectiveness and improvement of the proposed algorithm.
