Localization and estimation of multiple targets for MIMO radars using covariance matching techniques

A multiple-input multiple output (MIMO) radar system uses multiple antennas to simultaneously transmit independent signals to illuminate targets, and multiple antennas to receive the reflected signals. The covariance structure of the received signals is analyzed, and the covariance matching estimation technique (COMET) is applied to solve the problem of multiple-target localization and estimation in MIMO radar systems. The performance of the proposed method is validated by numerical simulations.
