In this paper, a novel orthogonal frequency-division multiplexing directional modulation (OFDM-DM) waveform synthesis approach is presented for multiple radar target sensing in free space. The DM waveforms have demonstrated unique advantages in radar sensing. Unlike the conventional DM waveforms synthesis approach, the proposed method here can simultaneously deliver information to multiple targets at a high data rate and detect their azimuth angles. The desired OFDM-DM signals can be constructed using the inverse fast Fourier transform (IFFT) modules with no need to re-synthesize the array excitation vectors for different DM symbols. Simulation results are provided to prove the efficacy of the proposed approach.
