Abstract

Angel estimation is considered for bi-static MIMO radar in the case where there exist both coherent and incoherent targets. Firstly, the bis-tatic MIMO radar data model is introduced and data covariance matrix is given. secondly, a matrix is formed using a column of the bi-static MIMO radar data covariance matrix. The rank of the formed matrix is only related to the number of the targets. Finally, the estimation of signal parameter via rotational invariance techniques (ESPRIT) algorithm is applied on the formed data matrix to estimate the direction of departure (DOD) and the direction of arrival (DOA). The numerical results show the effectiveness of the method.
