Abstract: Active jamming recognition is the mainstream of the anti-jamming methods of with respect to modern radar. Firstly, this paper classifies the active jamming methods from a new perspective. Especially, some emerging active jamming methods are included and their properties are also be analyzed. Secondly, worldwide literatures concentrating on the recognition of active jamming are summarized, and the results are stated in three subfields respectively i.e. features analysis of active jamming, features extraction and selection as well as classifier design.Last but not least, the paper summaries weaknesses still existed in recent research and predicted the future development tendencies about active jamming.
