摘要

摘要: 为了产生方位向初始位置和幅度可控的虚假运动场景，该文提出针对合成孔径雷达动目标显示(SAR-GMTI)的双干扰机幅度调制的虚假场景欺骗算法。双干扰机分别通过移频和延迟在指定位置产生相同的虚假运动场景。设置幅度比控制两幅虚假场景叠加后产生的各点的相位，达到初始方位向位置可控的目的。理论分析表明算法能够在指定位置产生初始方位向位置和幅度可控的虚假运动场景。然后分析了干扰效果和影响因素，建立了干扰算法的应用模型，给出了虚假运动场景的成像位置、方位向初始位置和幅度补偿系数的设置方法，并讨论了双站沿方位向间距对算法的影响。最后，仿真实验验证了算法的有效性。

Abstract: To control the initial azimuth position and the magnitude of the false moving scene, a false moving scene jamming method against Synthetic Aperture Radar-Ground Moving Target Indication (SAR-GMTI) is proposed based on double jammers and magnitude modulation. The identical false scenes can be generated in the desired position by the two jammers using delay and shift-frequency modulation. To control the initial azimuth position of the false moving scene, the magnitude ratio of the double scenes are set by controlling the phase of each false target which is generated after two false scenes are superimposed. Theoretical analysis shows that the false moving scene can be generated with the initial azimuth position and magnitude controllable. Next, the jamming effects and influencing factors are analyzed, and the application model of interference algorithm is established. Subsequently, the setting methods of the imaging position, the initial azimuth position and the magnitude compensation coefficient are presented. The jamming effect of the distance between the two jammers in azimuth is also analyzed. Finally, the validity of the proposed method is verified by simulation experiences.
