摘要随着目前电子战中雷达干扰技术的发展，多假目标干扰成为对抗雷达的一种重要的干扰样式。本文采用基于Zedboard的FPGA硬件平台对假目标干扰信号进行了实现。该方法可用于数字射频存储（digital radio frequency memory，DRFM）系统中处理雷达信号的干扰调制部分。DRFM系统可实现对雷达信号的高保真复制，同时针对雷达信号的大带宽、调制样式多变等特点，采用基于延时叠加的间歇采样转发干扰的方法设计实现假目标干扰信号，可快速精确地生成干扰信号，并很大程度降低对硬件系统的要求。验证结果表明，该方法可实现对雷达信号的假目标干扰。
Abstract：With the development of radar jamming technology in electronic warfare, multi-false target jamming has become an important jamming style against radar. This paper uses Zedboard-based FPGA hardware platform to realize false target jamming signal. This method can be used in the processing of radar signal interference modulation part of DRFM system. DRFM system can achieve high-fidelity replication of radar signal. At the same time, for the characteristics of radar signal such as large bandwidth, variable modulation patterns, the method of intermittently sampling and transmitting jamming based on delay superposition is adopted to design and realize false target jamming signal, which can quickly and accurately generate jamming signal and greatly reduce the requirements of the hardware system. The verification results show that this method can realize false target jamming to radar signal.
