Joint Radar-Communication Transmission: A Generalized Pareto Optimization Framework

Dual-functional radar-communication (DFRC) has been envisioned as a key enabler for number of emerging applications. Nevertheless, the intrinsic difference between communication and sensing functionalities imposed challenges in fully realizing promise technology. In this paper, we propose Pareto optimization framework multi-antenna DFRC system, where single transmitter with multiple antennas communicates users detects radar targets simultaneously. To begin with, define an achievable performance region that is built upon peak sidelobe (DPSL) spatial beampattern signal-to-interference-plus-noise ratio (SINR) each user, which proved to be compact normal. Then, formulate fairness-profile problem lowest acceptable level dual pre-defined direction attain boundary region. Also, provide bisection search algorithm solve polynomial complexity, prove its optimality can achieved by single-stream transmission. As further step, extend discussion beamforming design given hardware impairments. Finally, evaluate effectiveness proposed impact brought impairments numerical simulations.
