Robust Low-Sidelobe MIMO Dual-Function Radar–Communication Waveform Design
In multi-input–multi-output (MIMO) dual-function radar–communication (DFRC) systems, the inevitable amplitude–phase errors increase the sidelobe of transmit beampattern and distort the synthesized waveforms, which degrades both radar and communication performance. Due to this, a robust low-sidelobe...

| Summary: | In multi-input–multi-output (MIMO) dual-function radar–communication (DFRC) systems, the inevitable amplitude–phase errors increase the sidelobe of transmit beampattern and distort the synthesized waveforms, which degrades both radar and communication performance. Due to this, a robust low-sidelobe MIMO DFRC waveform design method is proposed. Firstly, a DFRC transmit signal model based on the uncertainty sets of amplitude–phase errors is established. The robust low-sidelobe MIMO DFRC waveform design problem is then formulated. In this problem, the sidelobe of transmit beampattern is minimized with the constraints on the mutual interference and the desired waveforms. To decrease the computational complexity, an alternating direction method of multipliers (ADMM)-based waveform design method is proposed, and the convergence is proved. Finally, some simulation results are presented to validate the effectiveness of the proposed method. |
