摘要
为提升信息化战争中对敌方雷达的干扰效率,提出了一种基于数字射频存储技术的间歇采样延时叠加干扰实现方法。基于该方法设计了雷达干扰信号生成系统,利用现场可编程门阵列中丰富的知识产权(IP)核资源,提取雷达信号参数信息、制定干扰策略,以间歇采样延时叠加的方式生成干扰信号。经试验验证,该方法能够高效、精准地干扰目标雷达。
In order to improve the efficiency of jamming to enemy radars in information war,an intermittent sampling delay superposition interference method based on digital radio frequency memory(DRFM)technique is proposed.Based on the method,a radar jamming signal generation system is designed.Using the abundant intellctual property(IP)core.resources in field programmable gate array(FPGA),the parameter information of radar signal is extracted,the jamming strategy is formulated,and the interference signals are generated by ntermittent sampling delay superpositin.The experimental reults show that the method can jam target radar eficiently and precisely.
