The optimal radar waveform for target information extraction had been derived to be the waterfilling solution using maximum Mutual information (MI) criterion, however, the optimal waveform is not a constantenvelop signal. In order to make full use of the system radiated power, a phase-iterative method to design the constant-envelop phase-modulated waveform is proposed. By minimizing the Euclidean distance between the designed waveform and the optimal one, the proposed method can achieve a small MI loss. The results of extensive simulations demonstrate that the MI loss of our approach can be less than 0.5nat when the signal duration is greater than 1μs.
