Abstract:The contest and confrontation of electromagnetic spectrum plays an essential role in the future information battlefield. Radar should also develop intelligent anti-jamming techniques to countermeasure the emerging agile and intelligent interference techniques. In this paper, the recent development of radar anti-jamming technology was decomposed into three parts: passive antagonism, active antagonism and cognitive antagonism. The representative literature was summarized and reviewed in terms of principles, implementation, and performance. Then, the concept of our ongoing research project——inducing and memorizing jammer was introduced, enriching the connotation of intelligent radar anti-jamming. Finally, the future technical requirements, battlefield scenarios and the development trends in this field were analyzed, which could inspire the future development of intelligent anti-jamming technology.
