在速度拖引欺骗干扰系统的设计中,需要快速产生干扰信号和修改干扰参数来应对复杂多变的电磁环境,干扰信号频率的准确度、稳定度以及干扰信号产生的快慢直接影响到干扰的效果。通过介绍速度欺骗干扰的基本原理、直接频率合成技术(DDS)的基本原理以及基于System Generator和DDS的多速度欺骗干扰的可编程门阵列(FPGA)的实现方法,提出了干扰模块的构造以及验证方法。测试结果证明DDS非常适合干扰频率的合成,System Generator非常适合多速度拖引欺骗干扰的FPGA实现。

In the design of the speed dragging deception jamming system,it is necessary to quickly generate the interference signals and modify the interference parameters to deal with the complex and varied electromagnetic environment.The accuracy and stability of the frequency of the interference signal,as well as the generation speed of the interference signal directly affect the effect of the interference.The basic principles of deception jamming and Direct Digital Synthesizer(DDS)are introduced,the implementation of Field Programmable Gate Arrays(FPGA)based on System Generator and DDS for multispeed deception jamming is presented.The construction of interference module is proposed and its verification methods are put forward.The test result proves that the DDS technology is very suitable for the synthesis of the interference frequency;and System Generator is very suitable for the FPGA implementation of multi-speed dragging deception jamming.
