Electronic warfare is the beginning of contemporary information-based warfare.The control of the battlefields multi-time, multi-space and multi-dimension information determines the outcome of the war.Decision-making issue in the information-based battlefield is different from the traditional combat command issue.Due to the complexity of the battlefield environment, the diversity of information and the information dependency of equipment, the research on interference decision-making is becoming more and more important.At present, the field of artificial intelligence is developing rapidly.The concepts of cognitive radio and cognitive electronic warfare have been proposed one after another.Based on the existing research results, this paper introduces the theory of cognitive interference decision-making, and sorts out relevant domestic and foreign literature.An analysis is made on three aspects of cognitive interference decision-making theory, namely, state recognition prediction, parameter control and resource scheduling.The commonly used theoretical methods and their existing shortcomings are summarized.Finally, the prospect of the radar cognitive interference decision-making is presented.
