摘　　要：Aim To get the theory base of designing FM fuze's jamming signal, its jamming mechanism was studied. Methods A sinusoidal FM fuze was analyzed in time domain and frequency domain and the concept of channel leak was presented. Results It was proved that information channel leak exists in FM fuze because of the nonlinear property of the mixer. The jamming signal was designed based on the channel leak and the jamming mechanism was analyzed in detail. Conclusion This kind of jamming signal can jam the sinusoidal FM fuzes effectively just depending on the jamming signal's feature itself. It's different from the traditional jamming way of simulating echo. Though the sinusoidal FM fuze was just analyzed, the principle is applicable to all FM fuzes. At the same time, it may be used as the reference for FM radar and communication countermeasures.目的　研究调频引信的干扰机理，获取调频引信干扰信号设计的理论依据． 方法　对正弦调频引信进行时域和频域分析，找出调频引信的信道泄漏机制，并利用数学分析设计干扰信号波形． 结果　证明了由于引信接收机混频器的非线性特性，调频引信中存在信道泄漏，具体设计了正弦调频引信的干扰信号． 结论　利用信道泄漏设计的干扰信号，不是使用传统的模拟回波的干扰方法，它仅依靠干扰信号自身的特点即可对正弦调频引信进行有效干扰． 作者在此只具体研究了正弦调频引信。
