【摘要】 本文提出一种基于互质递进时间调制方法的超高速灵巧式干扰技术。通过在射频通道中串联多级相位调制模块并控制其相互之间调制频率为质数,可以打破单级调制模块所存在的虚假目标规律性排布的问题,从而提升干扰系统抗识别能力。同时,基于频域卷积特性,相比单级调制模块,互质递进调制方法使谐波分量呈指数增加,从而有效提高虚假目标数量。更多还原

【Abstract】 An superhigh-speed smart jamming technology based on coprime progressive time modulation method is proposed in this paper.By controlling the modulated frequencies of the multi-level phase modulated modules in series in the radio frequency channel with prime numbers,the regularity of false targets caused by the single-level modulated module can be broken,which can enhance the anti-identification ability of the jamming system.Meanwhile,based on the frequency-domain convolution characteristics,compared with the single-level modulated module,the coprime progressive modulated method increases the harmonic components exponentially,which can increase the false targets’ number.更多还原
