摘　　要：针对侦察干扰一体化技术的需求、应用和发展,为解决大带宽同时侦收、干扰的问题,本文提出基于调制宽带转换器(Modulation wideband converter,MWC)技术的侦察干扰一体化设计。该设计包括多路压缩复用接收模块、压缩信号干扰生成模块、多路随机解混模块以及干扰发射模块。首先,将多路接收的信号采用MWC技术实现随机混频,经多路复合后实现单路模数转换器(ADC)采集,得到复合压缩信号;再对压缩信号加入指定样式的干扰生成压缩干扰信号;接下来完成单路数模转换器(DAC)的复合压缩信号随机解混;最后进行多路发射。仿真结果表明,该设计可以在较少的ADC与DAC通道下实现大带宽同时侦察与同时干扰,并验证了信噪比以及混频序列的相关性对干扰信号的影响。In response to the demand, application and development of integrated technology for reconnaissance and jamming,in order to solve the problem of simultaneous detection and jamming with large bandwidth,this article proposes an integrated design for reconnaissance and jamming based on Modulation Wideband Converter(MWC)technology. The design includes a multi-channel compression multiplexing receiving module,a compressed signal jamming generating module,a multi-channel random demixing module,and a jamming transmitting module. The design firstly uses the MWC technology to realize random mixing of the signals received by the multi-channel,and realizes the single-channel analogto-digital converter(ADC)reception after multiplexing to get the composite compressed signal. Then a specified pattern of jamming is added to the compressed signal to generate a compressed jamming signal.Next,the random demixing of the composite compressed signal of a single digital-to-analog converter(DAC)is completed. Finally,the signal is multiplexed. The simulation results show that the design can achieve large bandwidth simultaneous reconnaissance and simultaneous jamming with fewer ADC and DAC channels,and verify the influence of the signal-to-noise ratio and the correlation of the mixing sequence on the jamming signal.
