Unknown Radar signal recognition Technology Based on DS Evidence Theory

Aiming at the problem of insufficient prior data, the recognition ability of the classification model is solidified to a certain extent, and the recognition ability of unknown signals is limited. An unknown radar waveform recognition technology based on D-S evidence theory is proposed. Through the introduction of D-S evidence theory, the characteristics with instantaneous characterization ability and the characteristics of continuous characterization of the signal are used as judgment evidence, and a recognition framework based on the double evidence fusion theory is constructed to make a final judgment on whether the signal is unknown. After experimental simulation, this paper proposes. The accuracy of the method signal judgment is over 94%, which has been significantly improved.
