Multiple‐input multiple‐output (MIMO) radar systems allow array antennas to transmit different waveforms and enable flexible transmit beampattern synthesis. Most existing transmit beampattern synthesis methods focus on narrowband MIMO radar system configurations. In this study, the authors propose a novel technique to design transmit waveforms for wideband MIMO radar systems. This technique is based on the optimisation of the cross‐spectral density matrix and achieves a low peak‐to‐average power ratio as desired in practical radar systems. Simulation results are provided to verify the low PAR waveform design capability corresponding to arbitrary beampatterns.
