Robust interference waveform design in fuzzy colored noise based on mutual information

Abstract. Traditional waveform design methods mostly assume that the noise in the environment is Gaussian white noise. However, as the electronic warfare environment for the jammer becomes increasingly complicated, there is more likely to be a noise source that can emit fuzzy colored noise and a situation where the radar and jammer game, and the existing waveform design methods cannot meet jammer’s performance demand. Therefore, to reduce the radar’s estimation performance in complex environments, a fuzzy colored noise environment and a robust interference waveform design method under the hierarchical game model between the radar and jammer are proposed successively, which can minimize the mutual information of the radar echo signal and the target impulse response. Extensive simulation experiments show that the designed robust interference waveform can finally optimize the strategy of the jammer and provide a meaningful reference for the interference waveform energy allocation strategy in the future.
