Target Localization and Mutual Information Improvement for Cooperative MIMO Radar and MIMO Communication Systems

In this work, we study coexisting MIMO radar and MIMO communication systems, where the two systems work cooperatively. The radar shares its antenna positions and transmitted signals with the communication system. The communication system informs the radar about the antenna locations, as well as the statistics of the communication signals. Previous work has presented a performance gain for both the radar and communication systems in terms of target localization performance and mutual information. With the removal of the assumption about completely decoded communication signals at the radar receiver, this paper analyzes the performance metrics and shows that there is still a significant gain obtained through cooperation.
