摘要
经典的雷达抗干扰措施是针对传统的噪声压制干扰、杂乱脉冲干扰、同步脉冲干扰等人为干扰以及各种自然干扰而提出来的,在目前相参干扰已经基本替代传统人为干扰的情况下,分析了旁瓣对消、旁瓣匿影、动目标显示、动目标检测、频率捷变、重频捷变、射频掩护、恒虚警等经典雷达抗干扰措施在相参干扰情况下的抗干扰性能,得出了大部分经典抗干扰措施对抗相参干扰时性能下降甚至有的失效的结论。
Conventional radar anti-jamming measures have been put forward to degrade the effects of the traditional jamming, such as noise jamming, random pulse jamming, synchronous pulse jamming, and various natural interference. But considering that nowadays the traditional jamming has largely been supplanted by co herent jamming, the performance analysis of some conventional radar anti-jamming measures is conducted, in- cluding SLC/SLB, MTI/MTD, frequency agility, PRF agility, RF protection and CFAR under coherent jam- ming conditions, concluding that the performance of the most anti-jamming measures is degraded, with some even neutralized.
