Distributed Dual-Function Radar-Communication MIMO System with Optimized Resource Allocation

In this paper, we propose a novel distributed dual-function radar-communication (DFRC) MIMO system capable of simultaneously performing radar and communication tasks. The radar objective is to achieve the desired target localization performance whereas the communication objective is to optimize the overall data rate. The distributed DFRC MIMO system performs both objectives by optimizing the power allocation of the different transmitters in the DFRC system. A dictionary of radar waveforms is used at each transmitter and the communication information is embedded in the radar waveform by exploiting waveform diversity. The proposed strategy can serve multiple communication receivers located in the vicinity of the distributed DFRC MIMO system. Simulation results illustrate the performance of the proposed strategy.
