Simultaneous Multi-target Interference Technology Based on Digital Reconfigurability

复杂电磁环境中,随着作战目标受多雷达辐射源同时照射概率增大,雷达对抗中同时多目标干扰能力愈发重要。本文基于数字重构技术,实现常规模拟域中的多信道数字化处理。结合动态加载干扰数据库,实现灵巧式高逼真雷达假目标干扰信号产生。最后通过构建小型化和低功耗单通道数字干扰源模块,优化数字重构软件设计,实现同时多目标干扰能力验证。

In complex electromagnetic environment,as the probability of target being illuminated by multiple radar sources increases,multi-target interference capability is becoming more and more important in radar EW.This article aims at implementing multi-channel digitization processing in conventional analog domain based on digital reconstruction technology.Combined with the dynamic loading interference database,the smart high-fidelity radar decoy interference signal generation is realized.Finally,by building a miniaturized low-power single-channel digital interference source module and optimizing digital recon-struction software design,the verification of simultaneous multi-target interference capability is achieved.
