Multiple-Input Multiple-Output (MIMO) radar can achieve improved localization performance by employing a coherent processing approach with proper antenna positioning. Coherent processing, however, entails the challenge of ensuring phase coherence of the carrier signals from different distributed radar elements. In recent years, studies have shown how the performances of conventional phased-array radar can be improved by using the same approach. In this paper, the authors aim to address such a challenge by providing a systematic treatment of the phase synchronization problem in coherent MIMO radar systems.
