To further reduce the sidelobe level of waveforms for colocated multiple-input multiple-output (MIMO) radar, a random space-time coding (STC) method is proposed, which modulates prescribed waveforms at each transmission by a random permutation matrix multiplied by a random diagonal phase matrix. With the random modulation, sidelobes at different pulse repetition periods cannot be coherently accumulated, and then the overall sidelobe level drops significantly after coherent accumulation, as verified by numerical results.
