Multi-User Dual-Function Radar-Communications Exploiting Sidelobe Control and Waveform Diversity

Dual-function radar-communications technology has attracted significant attention in recent years. In this paper, we propose a novel technique for embedding communication information in radar waveforms by exploiting sidelobe control and waveform diversity. The proposed strategy can serve multiple communication receivers located in the sidelobe region. In addition to information broadcasting, the proposed approach enables multi-user access, i.e., transmitting distinct information streams to the communication receivers located in different directions. The developed technique also serves as a generalized mathematical framework for the existing sidelobe control-based techniques.
