Abstract
Abstract In this paper, we apply the 2-D Matrix Pencil Method(MPM) to the estimation of the direction of arrival(DOA) of multiple signals of interest(SOIs) in bistatic MIMO radar. The 2-D MPM shows remarkable performance under a low SNR environment and low computational complexity to estimate the DOA of multiple SOIs. Also, it is possible to estimate the direction of departure(DOD) which is an angle from transmitter to target. To verify the proposed algorithm, we applied the proposed algorithm to a uniformly spaced linear array(ULA) and compared the RMSE(Root Mean Square Error) of DOA and DOD under the various SNR with those of the 2-D Capon algorithm.Key words: MIMO Radar, DOA/DOD, 2-D Matrix Pencil Method O0FPQRSMTPMU0FV6W %TPXYWZV [\]0F^_QRM2012`+abcUNNdU[0F-e)345fghij.k abcUNlmnopUM(Department of Electronic Convergence Engineering, Kwangwoon University) * qcUNrs_tpUu(Division of Computer and Communications Engineering, Korea University)**TPMU0FV(Agency for Defense Development)Manuscript received May 8, 2014 ; Revised May 30, 2014 ; Accepted June 2, 2014.
