首先分析了对脉冲多普勒雷达实施假目标欺骗干扰的基本原理，通过分析得出为实现有效、逼真欺骗干扰，干扰系统必须满足的两个基本要求；然后详细介绍了一种应用先进结构数字射频存储器的欺骗干扰机系统的设计实现，它基于可编程门阵列可以实现实时快速傅里叶变换、多普勒调制和目标特性调制。

The basic principles of false target deception jamming against PD radar are discussed firstly. According to the analysis, it is deduced that two basic requirements for the jamming system must met in order to realize effective jamming. A deception jamming system is then introduced to which an advanced DRFM structure is applied. In this system, such function modules as real-time FFT, Doppler modulation and target-signature modulation are implemented based on FPGA.
