摘　　要：针对电子对抗领域中侦察干扰一体化的应用需求以及对宽、窄带雷达的作战需求,提出了一种基于数字收发信道化和数字并行上下变频结构的双模侦察干扰一体化架构。重点研究了无盲区50%重叠收发信道化的实现原理;并建立了仿真模型,评估了其对宽窄带信号的重构能力,在此基础上得出了两种模式协同工作的策略和依据。通过双模协同工作,不仅可实现对不同带宽信号的参数测量,还能自适应地进行数字储频并重构高线性度、低杂散的干扰信号。According to the application requirements of reconnaissance and jamming integration in the field of electronic countermeasures and the operational requirements of wide and narrow band radar,a dual-mode reconnaissance and jamming integration architecture based on digital transceiver channelization and digital parallel up-down conversion structure is proposed in this paper.The implementation of transceiver based on 50%overlapping channel overlap without blind area is studied;and simulation model is established and its ability to reconstruct wide and narrow band signals is evaluated.On this basis,the strategy and basis of the two modes working together are obtained.Through dual-mode cooperative work,it cannot only measure the parameters of signals with different bandwidth,but also adaptively store digital radio frequency and reconstruct jamming signals with high linearity and low spurious.
