Summary:In this paper, we consider a multicarrier waveform to perform simultaneously data transmission and radar sensing. On the radar receiver side, a state-of-the-art symbol-based algorithm generates a range-Doppler map affected by a self-interference phenomenon, potentially leading to target masking issues. Herein, we propose a successive interference cancellation procedure to enhance the radar performance while keeping a low-complexity implementation. We show that a very low reconstruction error is obtained in various scenarios. We also investigate the robustness of the proposed algorithm since it is subject to error propagation.
