Robust Waveform Design Based on Jammer Games in Cognitive Radar

Due to the uncertainties of radar target prior information in the actual scene, the waveform designed based on radar target prior information cannot meet the needs of parameter estimation. In order to ensure the performance of parameter estimation for the complex target model, a mutual information (MI)-based waveform design method which is robust to the model uncertainties under the hierarchical game model of radar and jammer is proposed in this paper. Simulation results indicate that the robust waveform design method ensures the parameter estimation performance effectively and provides useful guidance for waveform energy allocation.
