Abstract

Abstract

A method for multi-target localization based on polynomial rooting is developed in bistatic MIMO radar. Utilizing the property of transmit-receive steering vector, the two-dimensional (2-D) direction finding is transformed into two 1-D direction finding procedures. Then the polynomial rooting technique is employed to determine the 1-D direction. The proposed method avoids the conventional 2-D spectrum peak searching, and the estimated parameters are automatically paired without additional paring computation. Moreover the maximum number of targets resolved by this method is no smaller than the number of array elements. Numerical results verify the effectiveness of this method.
