Abstract

In this paper, we consider the problem of transmit/receive beamforming design for full-duplex communication in joint MIMO radar and communication systems. Downlink communication is achieved via embedding communication symbols into the emission of the MIMO radar system. We assume that the time reference of the MIMO radar platform is synchronized to that of the communication users. At the receiver, the uplink communication signal is mixed with the target return, clutter reflections, as well as additive noise. A new communication receive beamformer is developed which enables separating the uplink communication signal form the radar received signal even if the target and clutter returns share the same spatial angle as that of the communication user. MIMO radar employs transmit beamforming to mitigate the effect of signal-dependent clutter. Simulations results are used to shows the effectiveness of the proposed technique.
