摘要
雷达干扰系统是复杂电磁环境下的重要作战装备。干扰信号产生单元能够针对雷达信号的差异,产生针对性的干扰信号。本文阐述了干扰信号产生单元的系统组成,主要组件—频综、变频组件和DRFM组件的设计,并提出了设计中的关键技术——直接式数字频率合成及瞄频噪声产生单元的解决途径。测试结果表明,该干扰信号产生单元能够满足系统的技术指标要求。
Radar jamming system is an important combat equipment under complex electromagnetic environment. According to the difference of radar signal,jamming signal generation unit can generate the in-terference signal. The structure of jamming signal generation unit is expounded,and the design of frequency synthesis、variety frequency and DRFM synthesis has been realized. The key technology———the composite of direct digital frequency and aim frenqucy noise engendering unit have also been solved. The testing out-come shows that the jamming signal generation unit can satisfy the target demands of the system.
