Radar Performance of the OFDM Directional Modulation Waveforms for Joint Radar-Communication
2023 Cross Strait Radio Science and Wireless Technology Conference (CSRSWTC)(2023)
Abstract
The orthogonal frequency-division multiplexing (OFDM) waveforms have been intensively studied for joint Radar-communication (JRC), which can provide high data rates for wireless communication, and the range-doppler information of the Radar target also can be estimated. In this paper, the OFDM directional modulation (OFDM-DM) waveforms are proposed for the JRC, and its radar performance is investigated by a correlation-based Radar signal processing approach. It has been shown that compared with the OFDM JRC scheme the proposed OFDM-DM waveforms can suppress the interference from the non-target directions, which is validated via the simulation results.
