摘　　要：现代战争中电子对抗环境日益恶化,雷达干扰越来越复杂。如何避免雷达干扰,成为雷达工作的首要问题。低截获概率技术从根本上解决了此问题。论述了低截获概率的原理,推导了低截获改善因子,提出了低截获利用因子,对影响因素进行了量化分析,总结了低截获概率技术抗干扰,并从从雷达寂静、抗宽带干扰、积极对抗3个层面进行了仿真分析。结果表明低截获概率技术具有优良的抗干扰效果。In modern war, the electronic countermeasure environment becomes more and more bad- ly,the jamming to radar is more and more complicated. How to avoid the jamming to radar becomes the chief problem for the operation of radar. Low probability intercept （LPI） technology can solve this problem radically. This paper discusses the principle of LPI,deduces the improvement factor of low intercept,puts forward the use factor of low intercept,performs the quantizing analysis to in- fluence factors, summarizes the anti-jamming of LPI technology,performs the simulation and analy- sis from three aspects of radar silence, broadband anti-jamming, active confrontation. The results show that the LPI technology has good anti-jamming effect.
