摘　　要：箔条干扰是一种常用消极干扰,海军舰艇使用尤为有效,箔条干扰已成为海军舰艇装备的常规干扰手段。本文首先简要介绍了扩谱的基本原理及其特点和箔条干扰使用的四种基本方式。在此基础上简要分析了扩谱技术抗箔条干扰的原理,提出了实现扩谱系统要解决的几个技术关键。Chaff, as a passive interference, is widely used by the navy. In this paper the basic principles and particularities of spread spectrum are introduced, four modes to use chaff interference are expounded, and the performances in countering chaff interference with spread spectrum technology are analysed. Finally, some key problems of the spread spectrum radar homing head are discussed.
