Abstract

A MIMO-OFDM range reconstruction method based on cyclic prefix (CP) and its corresponding MIMO-OFDM waveform design for co-located MIMO radar systems are proposed. Our proposed MIMO-OFDM waveform design achieves the maximum signal-to-noise ratio (SNR) gain after the range reconstruction and its peak-to-average power ratio (PAPR) in the discrete time domain is also optimal, i.e., 0dB, when Zadoff-Chu sequences are used in the discrete frequency domain as the weighting coefficients for the subcarriers. Finally, simulation results are presented to verify the effectiveness of the proposed method.
