摘要：

In this letter, we modify the transmitted signal of the discrete frequency coding waveform with linear frequency modulation (DFCW-LFM) for multiple-input multiple-output (MIMO) radar from contiguous subpulses to an inconsecutive pulse train. The range-Doppler map is obtained by performing fast Fourier transform (FFT) after the transmit beamformer to detect the moving target. The cost function of the genetic algorithm used to optimize the carrier frequency sequence is obtained by minimizing both the range-Doppler sidelobes and cross-correlation peaks. Compared with the DFCW-LFM, the proposed waveform has lower autocorrelation sidelobes and cross-correlation for the delay within the subpulse duration.
