Abstract Both the spatial property and the temporal property should be considered in MIMO radar waveform design. It is a challenge to reduce the temporal sidelobe efficiently by designing the waveform in a single pulse, when the spatial property should be guaranteed. In this paper, an approach of pulse train code is proposed to suppress the temporal sidelobe, by which the spatial beampattern design and the temporal waveform design can be separated. The temporal sidelobe can be reduced without changing the beampattern. The numerical results show that the proposed method can reduce the range sidelobe in each Doppler channel efficiently with the consideration of Doppler frequency shift.
