Abstract:

Facing an increasingly complex electromagnetic environment, radar anti-jamming technology has become one of the key research directions in the radar field and has achieved rapid development. Among them, the main-lobe anti-jamming is a research difficulty that has attracted the attention of many scholars. Firstly, this paper outlined the mechanisms of radar jamming and anti-jamming in a complex electromagnetic environment and analyzed the reasons why main-lobe jamming is difficult to counteract. Then, the research progress of radar main-lobe anti-jamming technology was summarized from four aspects: jamming sensing technology, multi-domain anti-jamming technology, new system array radar anti-jamming technology, and intelligent radar anti-jamming technology. Furthermore, the development trend of future radar main-lobe anti-jamming technology was forecasted according to the current difficulties and the practical needs.
