Sidelobes of radar waveforms can cause many undesirable consequences. Inspirited by achievements in multiple‐input–multiple‐output radar, the authors study how to use and design a set of nearly orthogonal waveforms for monostatic radar with coherent accumulation operation to transmit at successive pulse repetition intervals (PRIs). As the range sidelobes at different PRIs cannot be coherently accumulated anymore during the coherent accumulation, the overall sidelobe level after coherent accumulation can be decreased significantly, which is verified by numerical results.
