DOA Estimation Based on Toeplitz Matrix for MIMO Radar
WU Meng
Abstract：Direction of arrival(DOA)estimation is an important aspect of MIMO radar,which have significant advantages in target detection and parameter estimation.Commencing with signal model of MIMO radar,the process of filtering in receiver was de?duced by transmitting orthogonal signals and a construction method of covariance matrix of received signals was proposed to realize signals decoherence.Based on the MUSIC algorithm,the DOA estimation performances were studied contrastively,the result indi?cated that the toeplitz-music algorithm proposed could estimate the direction of closer target and had a high accuracy under same conditions. The algorithm proposed gets good decoherence effect and estimation performances in low signal-to-noise ratio condi?tions.
