Maximum likelihood estimation of DOD and DOA for bistatic MIMO radar

► The maximum likelihood estimator of the target DOD and DOA for bistatic MIMO radar is derived under the unknown but deterministic framework. ► A compact expression of the CRB for angle estimation of the bistatic MIMO radar is given. ► Alternate projection is utilized to solve the MLE problem efficiently. ► An adapted space searching method is proposed to accelerate the AP algorithm and improve the estimation accuracy.
