Two-Dimensional Direction-of-Arrival Estimation for Trilinear Decomposition-Based Monostatic Cross MIMO Radar

الملخص EN

A low complexity monostatic cross multiple-in multiple-out (MIMO) radar scheme is proposed in this paper.

The minimum-redundancy linear array (MRLA) is introduced in the cross radar to improve the efficiency of the array elements.

The two-dimensional direction-of-arrival (DOA) estimation problem links to the trilinear model, which automatically pairs the estimated two-dimensional angles, requiring neither eigenvalue decomposition of received signal covariance matrix nor spectral peak searching.

The proposed scheme performs better than the uniform linear arrays (ULA) configuration under the same conditions, and the proposed algorithm has less computational complexity than that of multiple signal classification (MUSIC) algorithm.

Simulation results show the effectiveness of our scheme.
