Joint diagonalization based DOD and DOA estimation for bistatic MIMO radar

A novel joint direction of departures (DODs) and direction of arrivals (DOAs) estimator for bistatic multiple-input multiple-output (MIMO) radar via joint diagonalization direction matrices is proposed. The proposed estimator makes use of the MIMO array structure that enables to obtain an extended two-dimensional (2-D) array. Thereby, it may significantly increase the array degrees of freedom (DOFs) to estimate more targets than physical antenna elements. The computation complexity of the proposed method is also shown to be acceptable. Finally, asymptotic performance analysis and numerical experimental results are presented to demonstrate the effectiveness of the proposed method.
