在第二次世界大战中,箔条做为无源ECM,对付甚高频和超高频防空雷达是很有效的。在这以后的40年中,在微波电子战领城,它继续发挥重要作用,其中包括用于防御雷达制导的反舰导弹。世界各国普遍重视研究抗箔条干扰的方法,即箔条ECCM。主要介绍雷达的工作方法和箔条鉴别方法。此外,也谈及箔条鉴别系统的某些特殊问题,例如,有源ECM的影响,相干MTI与频率捷变不相容性以及跟踪雷达的箔条鉴别等。
In the Second World War, chaff as a passive ECM, to deal with VHF and UHF radar is very effective. For the next 40 years, it has continued to play an important role in the microwave electronic warfare leadership, including anti-ship missiles for defense of radar-guided missiles. All countries in the world attach great importance to studying anti-chaff interference methods, namely, chaff ECCM. Mainly introduces the working method of radar and chaff identification method. In addition, there are some specific problems with chaff identification systems such as the influence of active ECMs, incompatibility of coherent MTIs with frequency agility, and chaff identification of tracking radar.
