Abstract

In this paper, we analyze the performance of a joint MIMO node capable of simultaneous radar and communication functions. We derive outer bounds for rate regions of communication and radar estimation rate in terms of the communication link's information rate and the formulated radar estimation rate - a measure of how much information can be extracted from the radar return. We show that the knowledge of the communication signal can be utilized to improve the radar estimation rate. A legacy system's performance suffers as a radar target moves closer to a communications user due to increased interference from beamforming leakage power. However, we show that a joint system can benefit from this extra power. Since the joint system perfectly knows the radar and the communication signals, radar performance can be enhanced using communications returns from the radar target.
