  • 摘要: 该文提出了一种针对合成孔径雷达(SAR)的单比特多模态干扰方法,干扰机在截获SAR信号后,将其与单频阈值比较后量化为单比特数据。与传统高精度采样量化生成高逼真度假目标的欺骗干扰方法相比,单比特量化仅保留了数据的符号信息,降低了采样数据的位宽,达到简化系统、提升效率、降低成本的目的。同时,基于单频阈值的单比特量化在截获SAR信号中引入了丰富的谐波分量,通过合理设计阈值的幅度、频率与相位参数,可以将单频阈值泛化为多种阈值。不同阈值可以有效利用不同特性的谐波,进而达到单目标欺骗干扰、多目标欺骗干扰、射频干扰和类噪声干扰等多种干扰模态单一对抗或协同对抗、多模态间捷变的灵巧干扰效果。通过仿真实验定量分析了不同干扰模态下的干扰性能,验证了所提方法的有效性。
