Abstract EN
Aiming at the direction-of-arrival (DOA) estimation of two-dimensional (2D) coherently distributed (CD) sources which are coherent with each other, we explore the propagator method based on spatial smoothing of a uniform rectangular array (URA).
The rotational invariance relationships with respect to the nominal azimuth and nominal elevation are obtained under the small angular spreads assumption.
A propagator operator is constructed through spatial smoothing of sample covariance matrices firstly.
Then, combination of propagator and identical matrix is divided according to rotational operators, and the nominal angles can be obtained through eigendecomposition lastly.
Realizing angle matching automatically, the proposed method can estimate multiple DOAs of 2D coherent CD sources without spectral peak searching and prior knowledge of deterministic angular signal distribution function.
Simulations are conducted to verify the effectiveness of the proposed method.
