Development and Prospect of Airborne Radar Anti-jamming Technique

Jamming is one of the most important challenges airborne radar faces in the battle use, and so the anti-jamming capability becomes a key parameter used to evaluate the performance of airborne radar. First, the jamming environment that airborne radar encounters is introduced in this paper, then anti-jamming mind and advantages of anti-jamming strategy based on jamming environment are described. Further principles and implementations of some frequently-used anti-jamming methods are presented. Specially, recently focused anti-jamming techniques with polarimetry and with multistatic radar collaboration aimed at main-lobe jamming suppression are detailed. Finally, due to the progress of the jamming technique, future development tendency on the anti-jamming technique is analyzed.
